Bubble Growth in Cosmological Phase Transitions

Monday January 17th, 14:30hs - Seminar room

Speaker: Jose-Miguel No  (IPhT, Saclay)


FULL TITLE: "Bubble Growth in Cosmological Phase Transitions: Hydrodynamic Obstructions vs Runaway Bubbles". A cosmological first order phase transition can lead to many interesting phenomena, such as electroweak baryogenesis or the production of a stochastic background of gravitational waves.

Non-linear SUSY and MSS

Friday January 14th, 14:30hs - Seminar room

Speaker: Emilian Dudas (Ecole Polytechnique, Palaiseau)


Using the formalism of constrained superfields, we derive the general effective action of a light goldstino coupled to MSSM. The goldstino-induced couplings become important when the scale of supersymmetry breaking is low. We compute the Higgs potential and show that the (tree level) mass of the Higgs can be increased to the LEP bound for $\sqrt f\sim 2$ TeV to 7~TeV.

The ALBA synchrotron light source

Monday, January 17th, 12:00hs - Seminar room

Speaker: Ramon Pascual (CELLS-ALBA synchrotron, IFAE and UAB).


An introduction to third generation synchrotron light sources will be presented, with a special mention to ALBA, a project which started within the IFAE and which it is scheduled to start operation this year. Some examples of the capabilities of synchrotron light will be exposed, with a description of the seven beam lines of the first phase

Solar neutrino physics and the Borexino experiment

Monday December 13th, 12:00 - Seminar room

Speaker: Marco Pallavicini (Universita' di Genova / INFN)


Solar neutrino physics is an interesting field of research for both fundamental physics and solar physics. Low energy solar neutrinos, which provide 99% of the flux, are a unique probe to the Sun's interior and may help solving fundamental solar physics problem.

Leptogenesis without violation of B-L

Friday December 10th, 14:30 hs - Seminar room

Speaker: Juan Racker  (Universitat de Barcelona)



Leptogenesis is a very attractive mechanism to explain the baryon asymmetry of the universe because it connects this mystery with the smallness of neutrino masses. After an introduction to leptogenesis we will motivate and describe a simple model for low energy leptogenesis that conserves B-L.


New aspects of symmetry breaking in Grand Unified Theories

Thursday December 16th, 14:30 hs - Seminar room

Speaker: Luca Di Luzio  (SISSA, Trieste)


Only the minimal GUTs are usually subject to a thorough scrutiny by complementary observables such as the proton lifetime, the absolute neutrino mass scale and the matching with the effective SM flavor structure.
