UNIFICATION ofFUNDAMENTAL INTERACTIONS

THE G-W-S STANDARD MODEL

The HIGGS BOSON CONDENSATE

- SOMETHING fills the Universe it disturbs

Weak interactions making them SHORT-RANGED, while

it does NOT affect gravity or electromagnetism. - WHAT IS IT?
- Analogy with SUPERCONDUCTIVITY in a

superconductor the magnetic field gets repelled (

Meissner effect) and penetrates only over the

penetration length, i.e. the magnetic field is

short-ranged source which disturbs are

the boson condensates, Cooper pairs. - We are swimming in Higgs Boson Condensates

its value at the minimum of its potential

determines the masses of all particles!

Where all masses come from the HIGGS mechanism

THE HIGGS MECHANISM CAN BE REALIZED BY THE

PRESENCE OF AN ELEMENTARY HIGGS PARTICLE

2007)

quantitative and qualitative levels of New

Physics beyond SM

- QUANTITATIVE Taking into account the latest

WMAP data which in combination with LSS data

provide stringent bounds on ?DM and ?B

EVIDENCE FOR NON-BARYONIC

DM AT MORE THAN 10 STANDARD DEVIATIONS!! THE SM

DOES NOT PROVIDE ANY CANDIDATE FOR SUCH

NON-BARYONIC DM - QUALITATIVE it is NOT enough to provide a mass

to neutrinos to obtain a valid DM candidate LSS

formation requires DM to be COLD NEW

PARTICLES NOT INCLUDED IN THE SPECTRUM OF THE

FUNDAMENTAL BUILDING BLOCKS OF THE SM !

THE RISE AND FALL OF NEUTRINOS AS DARK MATTER

- Massive neutrinos only candidates in the SM to

account for DM. From here the prejudice of

neutrinos of a few eV to correctly account for DM - Neutrinos decouple at 1 MeV being their

massltltdecoupling temperature, neutrinos remain

relativistic for a long time. Being very fast,

they smooth out any possible growth of density

fluctuation forbidding the formation of

proto-structures. - The weight of neutrinos in the DM budget is

severely limited by the observations disfavoring

scenarios where first superlarge structures arise

and then galaxies originate from their

fragmentation

THE COSMIC MATTER-ANTIMATTER ASYMMETRY

PUZZLE-why only baryons -why

- NO EVIDENCE OF ANTIMATTER WITHIN THE SOLAR SYSTEM
- ANTIPROTONS IN COSMIC RAYS IN AGREEMENT WITH

PRODUCTION AS SECONDARIES IN COLLISIONS - IF IN CLUSTER OF GALAXIES WE HAD AN ADMIXTURE OF

GALAXIES MADE OF MATTER AND ANTIMATTER

- SM DOES NOT SATISFY AT LEAST TWO OF THE THREE

SACHAROVS NECESSARY CONDITIONS FOR A DYNAMICAL

BARYOGENESIS - NOT ENOUGH CP VIOLATION IN THE SM

NEED FOR NEW SOURCES OF CPV IN ADDITION TO THE

PHASE PRESENT IN THE CKM MIXING MATRIX - FOR MHIGGS gt 80 GeV THE ELW. PHASE TRANSITION OF

THE SM IS A SMOOTH CROSSOVER

NEED NEW PHYSICS BEYOND SM. IN PARTICULAR,

FASCINATING POSSIBILITY THE ENTIRE MATTER IN THE

UNIVERSE ORIGINATES FROM THE SAME MECHANISM

RESPONSIBLE FOR THE EXTREME SMALLNESS OF NEUTRINO

MASSES

MATTER-ANTIMATTER ASYMMETRY

NEUTRINO MASSES CONNECTION BARYOGENESIS THROUGH

LEPTOGENESIS

- Key-ingredient of the SEE-SAW mechanism for

neutrino masses large Majorana mass for

RIGHT-HANDED neutrino - In the early Universe the heavy RH neutrino

decays with Lepton Number violatiion if these

decays are accompanied by a new source of CP

violation in the leptonic sector, then - it is possible to create a

lepton-antilepton asymmetry at the moment RH

neutrinos decay. Since SM interactions preserve

Baryon and Lepton numbers at all orders in

perturbation theory, but violate them at the

quantum level, such LEPTON ASYMMETRY can be

converted by these purely quantum effects into a

BARYON-ANTIBARYON ASYMMETRY (

Fukugita-Yanagida mechanism for leptogenesis )

IS THE FINE-TUNING A REAL PROBLEM?

- WARNING THERE EXISTS AN EVEN LARGER HIERARCHY

OR FINE -TUNING OR NATURALNESS PROBLEM THE

COSMOLOGICAL CONSTANT PROBLEM ( THE MOTHER OF

ALL NATURALNESS PROBLEMS) SO FAR, WE SIMPLY

ACCEPT SUCH FINE-TUNING! - (OUTRAGEOUS) POSSIBILITY THE THEORY OF

EVERYTHING COULD BE UNIQUE, BUT WITH MANY

(INFINITE?) VACUA EACH GIVING RISE TO A DIFFERENT

UNI-VERSE ( MULTI-VERSE POSSIBILITY). WE CAN LIVE

ONLY IN THE VERY RESTRICTED CLASS OF THE

MULTI-VERSE SPACE WHERE THE BOUDARY

COSMOLOGICAL CONSTANT OR THE SCALE OF THE

ELW.SYMMETRY BREAKING AND, HENCE, THE HIGGS MASS)

EXHIBIT VALUES ALLOWING FOR THE CORRECT BBN,

LSS, OUR LIFE! - ANTHROPIC PRINCIPLE

HOW TO COPE WITH THE HIERARCHY PROBLEM

- LOW-ENERGY SUSY
- LARGE EXTRA DIMENSIONS
- DYNAMICAL SYMMETRY BREAKING OF THE ELW. SYMMETRY
- LANDSCAPE APPROACH (ANTHROPIC PRINCIPLE)

ROADS TO GO BEYOND THE STANDARD MODEL (I)

- 1) THERE EXISTS NO NEW PHYSICAL ENERGY SCALE

ABOVE THE ELW. SCALE gravity is an extremely

weak force not because of the enormous value of

the Planck scale, but because of the existence of

NEW DIMENSIONS beyond the usual 31 space-time

where (most of) the gravity flux lines get

dispersed - VISIBILITY AT LHC there exist

excited states of the ordinary particles (

Kaluza-Klein states) and some of them are

accessible at LHC (the lightest KK state may be a

stable particle and it can constitute the DM)

ROADS TO GO BEYOND THE STANDARD MODEL (II)

- 2) NO NEED TO PROTECT THE HIGGS MASS AT THE

ELW. SCALE THE HIGGS IS A COMPOSITE OBJECT (for

instance, a fermion condensate) WHOSE

COMPOSITENESS SCALE IS THE ELW. SCALE (cfr. the

pion mass case) - VISIBILITY AT LHC THERE EXIST NEW

(STRONG) INTERACTIONS AT THE ELW. SCALE WHICH

PRODUCE THE HIGGS CONDENSATE ( new resonances,,

new bound states, a new rescaled QCD at 1 TeV)

ROADS TO GO BEYOND THE STANDARD MODEL (III)

- 3) THE MASS OF THE ELEMENTARY HIGGS BOSON IS

PROTECTED AT THE ELW. SCALE BECAUSE OF THE

PRESENCE AT THAT ENERGY OF A NEW SYMMETRY, THE

SUPERSYMMETRY (SUSY) - VISIBILITY AT LHC WELL SEE

(SOME OF) THE SUSY PARTICLES AND THEIR

INTERACTIONS. THE LIGHTEST SUSY PARTCILE (LSP) IS

LIKELY TO BE STABLE AND PROVIDE THE DM. AT THE

SAME TIME, WE COULD DISCOVER SUSY AND THE SOURCE

OF 90 OF THE ENTIRRE MATTER PRESENT IN THE

UNIVERSE.

THE SUSY PATH

LOW-ENERGY SUSY

IS SUSY PRESENT IN NATURE?

- I think that it is very likely that SUSY is

present as a fundamental symmetry of Nature it

is the most general symmetry compatible with a

good and honest QFT, it is likely to be needed to

have a consistent STRING theory ( super-string),

in its local version ( local supersymmetry or

supergravity) it paves the way to introduce and

quantize GRAVITY in a unified picture of ALL

FUNDAMENTAL INTERACTIONS - Much more debatable is whether it should be a

LOW-ENERGY SYMMETRY ( i.e. effectively broken at

the elw. Scale) or a HIGH-ENERGY SYMMETRY (i.e.

broken at the Planck scale, or at the string

compactification scale)

IN SUSY WE NEED TO INTRODUCE AT LEAST TWO HIGGS

DOUBLETS IN ORDER TO PROVIDE A MASS FOR BOTH THE

UP- AND DOWN- QUARKS

BREAKING SUSY

- The world is clearly not supersymmetric
- for instance, we have not seen a scalar of

Q1 and a mass of ½ MeV, i.e. the - selectron has to be heavier than the electron

and, hence, SUSU has to be broken

) - IN THE MSSM, THANKS TO THE EXTENDED PARTICLE

SPECTRUM WITH NEW SUSY PARTNERS CARRYING B AND L,

IT IS POSSIBLE TO WRITE ( RENORMALIZABLE)

SUSY DM a successful marriage

- Supersymmetrizing the SM does not lead

necessarily to a stable SUSY particle to be a DM

candidate. - However, the mere SUSY version of the SM is known

to lead to a too fast p-decay. Hence,

necessarily, the SUSY version of the SM has to be

supplemented with some additional ( ad hoc?)

symmetry to prevent the p-decay catastrophe. - Certainly the simplest and maybe also the most

attractive solution is to impose the discrete

R-parity symmetry - MSSM R PARITY LIGHTEST SUSY

PARTICLE (LSP) IS STABLE . - The LSP can constitute an interesting DM

candidate in several interesting realizations of

the MSSM ( i.e., with different SUSY breaking

mechanisms including gravity, gaugino, gauge,

anomaly mediations, and in various regions of the

parameter space).

Bottino, Donato, Fornengo, Scopel

WHO IS THE LSP?

- SUPERGRAVITY ( transmission of the SUSY breaking

from the hidden to the obsevable sector occurring

via gravitational interactions) best candidate

to play the role of LSP - NEUTRALINO ( i.e., the lightest of the four

eigenstates of the 4x4 neutralino mass matrix) - In CMSSM the LSP neutralino is almost entirely a

BINO

GRAVITINO LSP?

- GAUGE MEDIATED SUSY BREAKING
- (GMSB) LSP likely to be the GRAVITINO ( it can

be so light that it is more a warm DM than a cold

DM candidate ) - Although we cannot directly detect the
- gravitino, there could be interesting signatures
- from the next to the LSP ( NLSP) for instance
- the s-tau could decay into tau and gravitino,
- Possibly with a very long life time, even of the

order of - days or months

HUNTING FOR DARK MATTER

INDIRECT DM SEARCHES

DIRECT DM SEARCHES

INDIRECT SEARCHES OF DM

- WIMPs collected inside celestial bodies ( Earth,

Sun) their annihilations produce energetic

neutrinos - WIMPs in the DM halo WIMP annihilations can take

place ( in particular, their rate can be enhanced

with there exists a CLUMPY distribution of DM as

computer simulations of the DM distribution in

the galaxies seem to suggest. From the WIMP

annihilation - -- energetic neutrinos ( under-ice, under-water

exps Amanda, Antares, Nemo, Antares,Nestor

future IceCube, KM3 ) - --photons in tens of GeV range ( gamma astronomy

on ground Magic, Hess, future ACT , Argo or in

space Agile, Glast) - --antimatter look for an excess of antimatter

w.r.t. what is expected in cosmic rays ( space

- Q professor, what is the probability that SUSY

is the right NP at the TeV scale? - A lets say, 5 or so
- Q But, professor, you said that SUSY is the most

likely NP, and now you say that it has 5 chance

to be it? - A yes, but you should consider that all the rest

has been proposed as NP has 5 per mille
