…et la diversification ?

Achille Stocchi

Difficile de définir « la diversification ». Je vais le faire dans le talk.

1) Higgs seems to be SM one.

2) No indication of New Physics (“direct” and “indirect”).

2a) Exclusion of existence of new particles in different scenarios at about the TeV scale

2b) “Couplings” in fermionic sector (with CKM and CP violation measurements) of the NP seems to be obeying to some particular symetry…

With the discovery of the Higgs boson, all the « expected » particles have been found

and

The SM with Higgs is a theory valid up to very high scale

IS THE STANDARD MODEL SATISFACTORY ?

Experimental problems !

The quantum stabilization of the Electroweak Scalesuggests that L~ 1TeV

Those are arguments of fine tuning…if the NP scale is at 2-3..10 (100?) TeV …naturalness is not at loss yet…

The problem of particle physics today is : where is the NP scale L ~ 0.5, 1…1016 TeV

In Addition…we do not know which kind of NP we could find.We have many models to extend the SM

“Relativistic path”

“Quantum path”

Crucial : Center-of-mass energy

Crucial : Luminosity

Two ways for searching for New Particles (Physics)

Look for discrepancy wrt SM on manydifferent measurements

Often not always this means rare decays

The quantum path

f

It is a game of couplings and scales

It worked quite well in the pastand at present.

(and many important experiments do not even appear in the previous plot)

J’identifie donc « la diversification » avec le Quantum Path

~1973 DISCOVERY of the Neutral currents.

~1970 charm quark from FCNC and GIM-mechanism K0 mm

~1973 3rd generation from CP violation in kaon (eK) KM-mechanism

~1990 heavy top from B oscillations DmB

~ 1990-2000 top mass determination through the Electroweak Precison Tests

~ 1990-2000 Higgs through the Electroweak Precision Test

All those are “Discoveries” and where crucial in the construction of the SM Lagrangian

Just few recent example :

5

Charm in ‘70 was NPBeauty in ‘70 was NPZ0 in ‘70 was NPTop in ‘90 was NPHiggs in ‘2010 was NP

6

For «quantum path» we have many examples.

OFTEN A « NOT DISCOVERY » IS VERY IMPORTANT

On a toujours fait « de la diversification… »

La question est plutôt pourquoi aujourd’hui on l’appelle

« de la diversification… »

J’espère que ce glissement sémantique ne nouspoussera pas a l’appeler bientôt

« de la diversion… »

J’identifie pour ce talk donc « la diversification » avec le Quantum Path*

* Bien sur au LHC et ILC on fait pleine de mesure « Quantum path »…

« Se divertir » a la même étymologie

Why should it work in the future

if NP particles are discovered at LHC we have to be able to study the flavour structure of the NP (“reconstructing” the NP Lagrangian)

to have the capability to explore NP scale beyond the LHC reach/direct searches

ef

bq

f

It is a game of couplings and scales

I try to be a bit more quantitative in a still reductive way

10I realised once the animiation I was finished that I could have addedBK*ee, some charm decay and/or CP, BD* t n

For measuring all these channels you need :

1. LCHb and upgrade (2015-2025)

2. Super Belle (2017-2025) + participation to the machine

3. NA62 (K+ p+ nn ) ( 2020) – still possible to join (also ORKA at FNAL but not recommanded

in P5)4. Experiments on K0 p0 nn KOTO at J-PARC [Br from 10-810-11

Possible to joint( 2020)

5. Phi-Factory (KLOE-small update) no future « really » foreseen

6. Tau-charm (BES III) no future « really » foreseen

7. (g-2)m (but…FNAL E989 and JPARC 2017/2018 ) [0.1ppm level and would move BNL 3σ to 7.5σ]

8. EDMs from muons, protons (ex: JEDI), neutron (nEDM), deutons (ex:JEDI), atoms…**

9. cLFV : MEG ( ->m e g) (actually running at PSI. Upgrade foreseen 2017-2025)

10. cLFV beyond 10-13 (SINDRUM II) COMET (J-PARC) , Mu2e (FNAL) and plans for 10-16

We have to Really a pity that…Interesting

We are present

In this « spirit » we should also add FCC (ILC) for ultimate study of some rare decays.

1) Experiments devoted to flavour physics in quark sector and to other rare hadron and leptons decays will allow to probe the existence of NP beyond the reach of direct experiment and if NP is hopefully discovered at LHC to study it.

2) French particle physics community is actually participating largely to LHCb-upgrade and to one nEDM experiment.

3) The participation to other programs (as in other countries) is really interesting because it could imply participation to machine, detector and physics few physicist and engineers will have a strong impact and visibility for the labs and the

institute (often entering program starting in relatively short time scale.) In my opinion this will not really affect the LHC (ATLAS, CMS) community I also think that it will allow to attract more young people. I think the financial impact is “quite small”

Point de réflexion : Isn’t it time to work in more than one experiment at the same time ?

Some final remarks for discussion

In addition I really think that these programs are also necessary if we want to move from LHC the next(s) big project.

SPARES

Deviation from precisely known SM value

Two classes of measurement

Measure non zero value where SM value ~ 0

Magnetic Dipole Moment / “g-2” ~ 0.002 but predicted in SM to 0.42ppm Present experimental uncertainty : Δ(aμ) = 63x10-11 (0.54 ppm)

Electric Dipole Moment / EDM : present limit (10-19 ) is poor compared to other EDMs. SM value ~ 10-36

Lepton flavour violating interactions. Present limits 10-11-12. SM ~ 10-50
