Research statement
Experimental particle physicist studying rare kaon decays at the NA62 experiment. At present my work is focused on firmware development for the NA62 trigger and data-acquisition system and the preparation for the measurement of lepton-flavour violating kaon decays.
I am involved in the following research directions:

LFV/LNV in K+ decays

The NA62 experiment in the North Area of the CERN SPS is now fully operational and taking data. The plan is to collect the highest statistics ever reached for Formula: 0 decays, of the order of Formula: 1 events in the fiducial decay region of the detector until the end of 2018. This high-intensity and high-precision setup makes it possible to probe a number of ultra-rare or forbidden decay channels. Of particular interest to the CP3 group are the LFV/LNV Formula: 2 and Formula: 3 modes.

Many BSM theories predict some degree of LFV, including Supersymmetry or the introduction of massive neutrinos. Furthermore, there are indirect hints for New Physics in the flavor sector, e.g. in the semileptonic decays of B-mesons. Explanations for the observed discrepancies predict effects of LFV in kaon decays. These particular LFV/LNV Formula: 4 processes which at present are not covered by another experiment provide an attractive opportunity to test the SM. Any observable rate for one of these modes would constitute unambiguous evidence for New Physics. Considering the statistics that will be available at NA62 the current limits on their branching-ratios could be improved by at least one order of magnitude.

NA62 computing

NA62 will look for rare kaon decays at SPS accelerator at CERN. A total of about $10^{12}$ kaon decays will be produced in two/three years of data taking. Even though the topology of the events is relatively simple, and the amount of information per event small, the volume of data to be stored per year will be of the order of ~1000 TB. Also, an amount of 500 TB/year is expected from simulation.

Profiting from the synergy inside CP3 in sharing computer resources our group is participating in the definition of the NA62 computing scheme. CP3 will be also one of the grid virtual organization of the experiment.
