Neutrino masses from Kahler operators and broken SUSY

Friday July 8, 14:30hs - Seminar room

Speaker: Filipe R. Joaquim  (CFTP, Lisbon)

Abstract:

I will present a SUSY scenario in which neutrino masses are generated by effective d=6 operators in the Kahler potential, rather than by the standard d=5 superpotential operator.

LHC tests of the Tevatron t tbar asymmetry

Wednesday July 6, 14:30hs - Seminar room

Speaker: J.A. Aguilar-Saavedra  (Universidad de Granada)


Abstract:

The forward-backward asymmetry measured by CDF may be a hint of physics beyond the Standard Model. Models accommodating this asymmetry will undergo stringent tests from t tbar production at LHC, especially the measurement of the high-mass tail and the charge asymmetry.

JULY 2011 - LHC already reaches its collisions goals for 2011

In the first half of 2011 LHC has delivered more than one fb-1 (inverse femtobarn) of integrated luminosity to the experiments. One inverse femtobarn corresponds to approximately 70 million million collisions. In fact, LHC crossed the one inverse femtobarn goal set in 2010 for the whole 2011 run on June 16th, just three months since the beginning of this year's run. This shows the excellent performance of the accelerator and brings nearer the moment when new physics may show up. Read more on the CERN press release.

The Higgs: status and perspectives

Friday July 1st, 14:30hs - Seminar room

Speaker: Abdelhak Djouadi (Universite de Paris Sud, Orsay)

Abstract:

I will summarize the status of the Higgs boson in the Standard Model and its supersymmetric extension with a focus on Higgs production at hadron colliders and the associated theoretical uncertainties.

Non-Abelian Semi-Local Vortices, from (S)QCD to Condensed Matter

Friday June 17, 14:30hs - Seminar room

Speaker: Walter Vinci (University of Minnesota)

Abstract:

I will present some of my contributions to the study of BPS string-like solutions in supersymmetric gauge theories with extended supersymmetry. In particular, I will review the concepts of non- Abelian and semi-local vortices.

JUNE 2011 - Electron neutrino appearance at T2K

The T2K experiment, whose primary purpose is to study neutrino interactions at a large distance from their source, has detected 6 electron neutrino candidate events based on the data collected before March 11, 2011. For the first time, it was possible to observe an indication that muon neutrinos are able to transform into electron neutrinos over a distance of 295 km through the quantum mechanical phenomena of neutrino flavor oscillations.

Tsukuba, February 24, 2010. The T2K experiment, whose primary purpose is to study neutrino interactions at a large distance from their source, has detected 6 electron neutrino candidate events based on the data collected before March 11, 2011. For the first time, it was possible to observe an indication that muon neutrinos are able to transform into electron neutrinos over a distance of 295 km through the quantum mechanical phenomena of neutrino flavor oscillations.
