I am a final year Ph.D student working on the BABAR experiment which is based at SLAC (California). The aim of the BABAR experiment is to study CP-violation through the decays of B-mesons which are produced at the Y(4s) resonance using an asymmetric e+e- collider facility (PEP-II). I have been involved in the operation of the Electro magnetic Calorimeter Trigger and the Online Prompt Reconstruction systems during the period I have spent at SLAC. I am also working on the partial reconstruction of the decay channel B0 -> D*- a1+. Up to now we have provided an improved measurement of the Branching Fraction for this decay. Currently I am working on mixing and lifetime studies with this channel.

LHCb is one of the four experiments which will be built for the new LHC collider. It is a dedicated experiment for B-physics. LHCb is designed to study CP-violation and rare decays. I am doing a Ph.D. study on this detector. Using computer simulations I analyse the expected performance of the Bs -> Ds K decay channel. This channel is particularly sensitive to the angle gamma of the CKM matrix. LHCb is capable of retrieving a very high statistics sample of Bs -> Ds K events. Besides this, I am also involved in the track reconstruction. This involves developing the software as well as optimising the detector configuration.

For my Ph.D.thesis I am working on the analysis of data from proton-proton and proton-nucleus interactions at intermediate energies(1-3 GEV/c incident proton momentum),and the preparation of the equipment for future investigation of eta-meson production and eta-meson- nucleus final state interactions at energies close to threshold. Study of these reactions is expected to provide important information on the possibility of formation of eta-mesic nuclei,i.e. nuclei with quasi-bound eta-mesons in the final state. The measurments will be perfomed with the GEM detector at the COSY accelerator - IKP Germany. I am also working on the setting and testing of the necessary software for data processing and analysis.

I am a 2nd-year Ph.D. student and I am working at KLOE, a high energy physics experiment at the e+e- collider DAFNE in Frascati (Italy). My analysis is being carried out on the statistic collected in last two years at KLOE and is focused on some measurements in the charged Kaons physics: the charged Kaon lifetime (including CPT violation tests), the branching ratio of the K+ in pi+ pi0 pi0, and the asimmetries in the Dalitz plot parameters of the same decay. I am also involved in the KLOE software, where I took part in the online monitoring and in some Monte Carlo tools.
