## SEMINAR: Recent progress in massless and massive event shapes

March 19 2015, 11:30am - Seminar room

Speaker: Vicent Mateu (Vienna U)

Abstract : In this talk I will give an overview of our recent developments in the theoretical description of the event shapes, and will discuss the results obtained in recent analyses for the determination of the strong coupling constant.

## SEMINAR: Gauge-Higgs unfication after the discovery of the Higgs particle

March 13 2015, 2:30pm - Seminar room

Speaker: Chong-Sa Lim (Tokyo Woman's Christian Univ.)

Abstract : The Higgs has turned out to be ''light", whose mass being of the order of the weak scale. This suggests that the Higgs self-coupling is governed by gauge principle.

## SEMINAR: Hamiltonian Truncation methods: solving strongly-coupled QFTs numerically

March 6 2015, 2:30pm - Seminar room

Speaker: Lorenzo Vitale (EPFL Lausanne)

Abstract : In this talk I will present the Hamiltonian Truncation method, one of the simplest realizations of the ''exact diagonalization'' techniques used to solve strongly-coupled QFTs numerically, as opposed to standard lattice Monte Carlo methods.

## SEMINAR: Three tales for three scalars

February 27 2015, 2:30pm - Seminar room

## SEMINAR: Heavy quark masses from QCD sum rules

February 20 2015,12:00pm -  Seminar room

Speaker: Pere Masjuan (Mainz U)

Abstract :  The precise knowledge of the heavy quark masses plays an important role in many phenomenological applicants, from Higgs physics to B-meson and charmonium decays. On top, quark masses are fundamental parameters of the Standard Model Lagrangian.

## SEMINAR: Signals of natural SUSY

February 13 2015, 2:30pm -  Seminar room

Speaker: Antonio Delgado (Notre Damme U)

Abstract :  In this talk I will present a couple of scenarios of natural SUSY paying special attention to their LHC signatures. The first one is a top-down model for heavy stops and the second one is a phenomenological model for light neutralinos.

## SEMINAR: Phenomenological approaches of inflation and their equivalence

January 30 2015, 12:00pm -  Seminar room

Speaker: Lotfi Boubekeur (Valencia U & IFIC)

Abstract :   Inflation is the dominant paradigm to explain the initial conditions of our universe, yet this attractive paradigm is still lacking robust observational confirmation.

## SEMINAR: Physical parameters of the electroweak crossover

January 23 2015, 2:30pm -  Seminar room

Speaker: Michela D'Onofrio (Helsinski U)

Abstract :  We use large-scale lattice simulations to compute the rate of baryon number violating processes (the sphaleron rate), the Higgs field expectation value, and the critical temperature in the Standard Model across the electroweak phase transition temperature.

## SEMINAR: Dark Nuclear Physics

January 9 2015, 2:30pm

Speaker: Matthew Mccullough (CERN)

Abstract : I will discuss the possibility of nuclear physics in the dark sector with a focus on the types of scenarios in which dark nuclear physics could arise and how this might influence dark sector cosmology and phenomenology

## SEMINAR: New ways to search for right-handed current in $B\to \rho \ell \bar\nu$ decay

December 19 2014, 2:30pm - Seminar room

Speaker: Sascha Turczyk (U Mainz)

Abstract : An interesting possibility to ease the tension between various determinations of $|V_{ub}|$ is to allow a small right-handed contribution to the standard model weak current.  The present bounds on such a contribution are fairly weak.
