SEMINAR - Hadron mass effects to event shape power corrections

Friday January 25th 2013, 2:30 pm - Seminar room

Speaker: Vicent Mateu (IFIC)

Abstract: In my talk I will address the issue of mass effects on power correction to event shape distributions.

MAM SEMINAR - Soft Collinear Effective Theory (SCET) and event shapes

Thursday January 24th 2013, 2 pm - Coffee room

Speaker: Vicent Mateu (IFIC)

Abstract: ST in an effective field theory designed for describing processes involving collimated jets. The non-local nature of SCET makes it harder than the usual EFT's.

SEMINAR - UV Completions of Composite Higgs Models with Partial Compositeness

Friday January 18th 2013, 2:30 pm - Seminar room

Speaker:  Marco Serone (SISSA & INFN, Trieste)

Abstract: Models where the Higgs field is a composite pseudo Nambu-Goldstone Boson (NGB) and the other Standard Model (SM) fields are partially composite (partial compositeness) represent one of the most interesting scenarios of new physics beyond the SM.

COLLOQUIUM - Quo Vadis Higgs?

Monday January 14th 2013,  12 pm -  Seminar room

Speaker: Cristophe Grojean (IFAE - ICREA)

Abstract: After 48 years of desperate searches, the most wanted elementary particle, the Higgs boson, or something that wickedly looks like it, has finally been caught by the ATLAS and CMS experiments.

SEMINAR - Inflation, non-Gaussianity and conformal symmetries

Wednesday December 5th 2012, 2:30 pm - Seminar room

Speaker: Toni Riotto (Geneva University)

Abstract: Non-Gaussianity, i.e. the non-Gaussian contributions to the correlations of the cosmological fluctuations, is an important probe of the physics of inflation.

SEMINAR - Gravitational waves from first order phase transitions

Friday November 30th 2012, 2:30 pm - Seminar room

Speaker: Chiara Caprini (Institut de Physique Théorique, CEA Saclay)

Abstract: Gravitational waves can represent a unique probe of the very early universe. After an introduction about the main properties of the stochastic background of gravitational waves from primordial sources, the seminar concentrates on the gravitational wave signal from a primordial first order phase transition.

SEMINAR - Issues in alphas determinations from tau decays

Friday November 23rd 2012, 2:30 pm - Seminar room

Speaker: Diogo Boito (Technische Universität München)

Abstract: We will discuss recent developments in the QCD description of hadronic tau decays with emphasis in the perturbative contribution. Various moments of the hadronic spectral functions have been employed in the determination of the strong coupling alpha_s from tau decays.We will analyse the behaviour of their perturbative series under different assumptions for the large-order corrections and for the renormalization group improvement of the series.

SEMINAR - Current status of gamma-ray dark matter searches with Fermi/LATst

Wednesday  November 21st 2012, 3 pm - Seminar room

Speaker: Miguel Ángel Sánchez Conde , KIPAC- SLAC National Accelerator Laboratory

Abstract: Since its launch in 2008, the NASA Fermi satellite has been extensively searching for dark matter induced gamma-rays. Indeed, Fermi/LAT results have made significant inroads in limiting the standard “WIMP miracle” dark matter scenario, providing the most stringent limits in the annihilation cross section so far.

SEMINAR - Lattice input on the tau V_us determination puzzle

Friday November 16th 2012, 2:30 pm - Seminar room

Speaker: Kim Maltman (York University (CA) and Adelaide University (Aus)

Abstract: Recent determinations of V_us from flavor-breaking sum rules involving strange and non-strange hadronic tau decay data yield values significantly lower than expectations based on three-family unitarity, and also than those obtained from analyses of K_{ell 3} and the ratio of K_{mu 2} to pi_{mu 2} decay widths.

MAM SEMINAR - BSM theories face Higgs coupling data

Thursday  November 15th 2012, 2 pm - Coffee room

Speaker: Sandeepan Gupta

Abstract: In this talk I will discuss how to probe Beyond Standard Model theories with Higgs coupling data.
