Talk: Perspectives on the ATLAS Distributed Computing for the LS1 and beyond
Alexei Klimentov.  BNL, CERN

Tuesday,   March 5 ^th, 2013   ……………………….  at   IFIC’s seminars room, 11:00 am 
Abstract: This talk will summarize the Software development and operational experience and improvements of the ATLAS Distributed Computing in the past years. Grid model was successfully deployed for all HEP experiments and after the first two years of very successful LHC data-taking and processing on the Grid we need to assess our experience and to find a good balance between stability and innovation.

Several Research and Development (RnD) pilot projects were launched by ATLAS (and HEP) computing communities, namely ‘cloud computing’, data storage federation. HEP experiments have also adopted data popularity model and it allows to migrate from planned data placement to the dynamic data placement model.

This talk will also present an overview of HEP experiments computing model evolution and increasing role of networking as one of major resources (in addition to storage and CPU) which should be taken into account by workload management and data management systems.

Seminar:   Right-handed Neutrinos and the (Dark Sector of the) Universe
Nick E. Mavromatos. King’s College London, UK

Friday, February 15 ^th, 2013 ……. 15:00 PM Theoretical Physics Seminar room
Abstract: I discuss the role of neutrinos, in particular right-handed sterile ones, in contributing to the dark sector of the Universe, especially in playing the role of dark matter. I start from a simplest extension of the standard model, proposed by Shaposhnikov and collaborators, which involves three right-handed Majorana massive neutrinos, and exploit astrophysical and cosmological constraints on the lowest of these extra states in order for it to be the dark matter candidate. This is consistent with current constraints, provided the mass ……..read more

Seminar:   Neff and Neutrino Oscillations: role of the sterile neutrino and of neutrino asymmetry
Ninetta Saviano, Univ. Hamburg & Univ. Naples

Tuesday, February 19 ^th, 2013 ….. 12:00 at Basement Floor’s Room, Institutes Building (UVEG)
Abstract: In the last recent years different anomalies observed in short-baseline neutrino oscillation experiments seem to point towards the existence of light sterile neutrinos. These sterile neutrinos can also be produced in the early universe by oscillations of the active neutrinos and can affect different cosmological observables. In particular, sterile neutrinos can contribute as extra radiation to the non electromagnetic energy density, usually expressed in terms of the effective number of thermalized neutrino species Neff. In order to compare the forthcoming Planck data on extra radiation with the possibility of sterile neutrino it is necessary a systematic study of their abundance with parameters consistent with the interpretations of short-baseline neutrino oscillation experiments. At this regard, we perform a detailed study of the flavor evolution in different active-sterile oscillation schemes, in presence of dynamical primordial neutrino asymmetries. Moreover we discuss the impact on BBN of significant distortions produced in the electron (anti)neutrino spectra in presence of large asymmetries.

Seminar:     The Inert Doublet Model, a model for scalar dark matter 
Laura López-Honórez, MPI  Heidelberg

Wednesday, January 30^th, 2013   11:00 AM ……  at IFIC
Abstract: The Inert doublet model is a very simple and yet very rich extension of the standard model giving rise to viable scalar dark matter candidate. I will discuss the phenomenology of the Inert dark matter  and study the constraints coming from direct and indirect detection searches as well as constraints from Higgs searches on the viable parameter space.
