Leptogenesis without violation of B-L

Friday December 10th, 14:30 hs - Seminar room

Speaker: Juan Racker  (Universitat de Barcelona)

 

Abstract:

Leptogenesis is a very attractive mechanism to explain the baryon asymmetry of the universe because it connects this mystery with the smallness of neutrino masses. After an introduction to leptogenesis we will motivate and describe a simple model for low energy leptogenesis that conserves B-L.

 

New aspects of symmetry breaking in Grand Unified Theories

Thursday December 16th, 14:30 hs - Seminar room

Speaker: Luca Di Luzio  (SISSA, Trieste)

Abstract:

Only the minimal GUTs are usually subject to a thorough scrutiny by complementary observables such as the proton lifetime, the absolute neutrino mass scale and the matching with the effective SM flavor structure.

New physics from W polarisation in top quark decays

Tuesday December 14th, 14.30hs - Seminar room

Speaker: José Bernabeu (IFIC, Valencia)

Abstract:

From the most general Wtb vertex arising from dimension-six gauge invariant effective operators, I discuss the density matrix for the decay of a polarised top quark into a polarised W boson and a b quark.

Searching for New Physics with Top Quark Decays

Friday December 3rd, 14:15hs - Seminar room

Speaker: Jernej F. Kamenik (Jozef Stefan Institute, Ljubljan)

 

Abstract:

We analyze possible new physics signals in the decays of the top quark within an effective field theory approach. In particular, we compute the branching ratios for the rare top quark decays t to c gamma and t to c Z mediated by effective flavor changing neutral couplings at the next-to-leading order in QCD including the effects due to operator mixing.

Geneva, 26 November 2010. After less than three weeks of heavy-ion running, the three experiments studying lead ion collisions at the LHC have already brought new insight into matter as it would have existed in the very first instants of the Universe’s life.

 

The structure of 4D Conformal Field Theories

Friday November 26th, 14:30hs -  Seminar room

Speaker: Slava Rychkov  (ENS & UPMC, Paris)

Abstract:

I will review the status of the program, initiated a few years ago by the speaker and R. Rattazzi, of putting model-independent bounds on the structure of 4D CFTs by using OPE associativity and unitarity. I will also discuss applications to BSM phenomenology.

The emergence of Dirac Pyisics in Graphene

Tuesday, November 23rd, 14:00hs. - Coffee room

Speaker: Alessio Celi (UB)

Abstract:

After a very brief introduction to the genesis of the material and to the (apparent) clashing with the Mermin-Wagner theorem, I will show that many of the surprising experimental properties, like the relativistic dispersion relation of the quasi-electrons, can be easily explained by the tight-binding approx (Hubbard model).
