## Three-magnetic fields

Friday April 13, 14:30 hs - Seminar room

Speaker: Federico Urban (University of British Columbia, Canada)

Abstract:

I will discuss a qualitatively new possibility for the generation of cosmic magnetic fields in the context of inflation.

Minimal Flavor Violation without R-parity

Friday March 30 , 14:30 hs - Seminar Room.

Speaker: Marco Nardecchia (DIAS, Denmark)

Abstract:

We study the extension of the Minimal Flavour Violation (MFV) hypothesis to the MSSM without R-parity. The novelty of our approach lies in the observation that supersymmetry enhances the global symmetry of the kinetic term and in the fact that we consider as irreducible sources of the flavour symmetry breaking all the couplings of the superpotential including the R-parity violating ones. If R-parity violation is responsible for neutrino masses, our setup can be seen as an extension of MFV to the lepton sector.

## Higgs searches with the CMS detector at LHC

Friday March 30 , 12:00 hs -  Seminar Room.

Speaker: Prof. Guenakh Mitselmakher (University of Florida)

Abstract:

The results of the Higgs searches with the CMS detector at LHC are presented. Higgs-->4l searches in the low mass region are discussed in more details.

## Chiral effective theory with a light scalar and lattice QCD

Friday March 23, 14:30hs -  Seminar room

Speaker: Pedro Talavera (Universitat de Barcelona)

Abstract:

We extend the usual chiral perturbation theory framework to allow the inclusion of a light dynamical isosinglet scalar.

## SUSY searches at LHC, presented at Moriond EW 2012

Wednesday March 21, 14:00hs - Seminar room

Speaker: Ernesto Arganda

(Coffee will be served 10min before in the TH common room)

## Interpreting Higgs results

Friday, March 16, 14:30hs - Seminar room

Abstract:

I will present an analysis of the 2011 LHC Higgs data in the context of an effective low-energy theory of the Higgs boson. The focus will be on searches in the Higgs to 4 leptons and Higgs to diphoton channels.

## News from last week's Moriond conference on EW interactions

Thursday March 15, 15:00hs - Seminar room

Speaker:  Carla Biggio

## The static energy renormalon from high order perturbative expansions

Friday March 9, 14:30hs -  Seminar room

Speaker: Clemens Bauer (University of Regensburg, Germany)

Abstract:

Using Numerical Stochastic Perturbation Theory (NSPT), we calculate the static self-energy of SU(3) gauge theory up to order $\alpha^{20}$ .

## The Next-Generation Infrared Spectrograph for the GTC

Wednesday March 7, 12:00hs - Seminar Room

Speaker : Stephen S. Eikenberry (University of Florida)

Abstract:

MIRADAS is a near‐infrared multi‐object R=20,000 echelle spectrograph for the 10.4‐meter Gran Telescopio Canarias.

## Neutron stars as laboratory for dense matter

Friday, March 2, 14:30hs - Seminar room

Speaker: Laura Tolos (ICE/UAB)

Abstract:

Neutron stars are an excellent laboratory for testing matter under extreme conditions. In particular, a lot of emphasis has been invested in understanding the interior of neutron stars and the equation of state of the different possible phases since its direct consequences for the mass-radius relationship of neutron stars as well as cooling processes.
