Magnetic fields, chiral anomalies and lepton asymmetry

Friday October 5th, 14:30hs. - Seminar room

Speaker: Oleg Ruchayskiy (CERN)


It is generally believed that the ground state of the Standard Model at high temperatures is homogeneous and isotropic. This assumption underlies the description of many important processes in the early Universe.

Neutrinos and dark matter

Friday June 29 14:30hs - Seminar room

Speaker: Viviana Niro (UB)


I review the state of the art for candidates of Dark Matter, focusing also on the possibility that keV-sterile neutrinos constitute the Dark Matter particle. In this context, I summarize several models that can explain the required mass pattern in the right-handed neutrino sector.

Seiberg duality versus hidden local symmetry

Friday June 22, 14:30hs -  Seminar room

Speaker: Steven Abel (Durham, UK)


It is widely believed that the emergent magnetic gauge symmetry of SQCD is analogous to a hidden local symmetry (HLS). I explore this idea in detail, and show how one can derive the (spontaneously broken) magnetic theory by applying the HLS formalism to spontaneously broken SU(N) SQCD.

Flavor Physics within and beyond the SM: present status and future perspectives

Friday May 25, 12:00hs - Seminar room

Speaker: Paridi Paradisi (CERN)


We summarize the present status of our knowledge of flavor within and beyond the SM giving particular emphasis on its phenomenological aspects. Possible hints for New Physics, like CP violation in charm and B systems, are outlined and interpreted within specific beyond SM scenarios monitoring, at the same time, their implications in other correlated low energy observables.


Closing in on Asymmetric Dark Matter

Monday May 21, 14:30hs - Seminar room

Speaker: James Unwin (Oxford, UK)


I will first provide an overview of the Asymmetric Dark Matter (ADM) framework. Following this I shall argue that experimental constraints strongly suggest that in models of ADM the dark matter must be part of a richer hidden sector of interacting states. This talk is based mainly on arXiv:1203.4854.


Dark radiation and sterile neutrinos

Friday May 18, 14:30hs - Seminar room

Speaker: Jan Hamann  (University of Aarhus, Denmark)

Divendres, 18 de maig de 2012 a les 14.30h


Recent cosmological data hint at the possible presence of an excess energy density in relativistic particles, dubbed "dark radiation".

New hadronic form factors in TAUOLA

Friday May 11, 14:30hs - Seminar room

Speaker: Pablo Roig (IFAE)


We present the new hadronic currents implemented in the Monte Carlo generator TAUOLA, which is the standard library for analysing tau lepton measurements: both in high-energy experiments (such as LHC) and in the heavy-flavour factories (BaBar and Belle and future super-B).

Relations between anomalous and even-parity sectors in AdS/QCD

Friday May 4, 14:30 - Seminar room

Speaker: Juan Jose Sanz Cillero (Universita' di Bari)


In arXiv:1010.0718 [hep-ph] Son and Yamamoto found an interesting relation between the odd and even-intrinsic parity sectors of QCD for the class of holographic models where chiral symmetry is broken though IR boundary conditions.

Self-healing of unitarity violations

Wednesday April 25, 14:00 hs. - Coffee room

Speaker : Matthias Jamin (IFAE)






Predicting the Higgs mass from Inflation models

Friday April 20, 14:30hs  -  Seminar room

Speaker: Alessio Notari (Universitat de Barcelona)


For a narrow band of values of the top quark and Higgs boson masses, the Standard Model Higgs potential can develop a false minimum at energies of about 10^15-10^16 GeV, where primordial Inflation could have happened.
