My experience in this field is the development of an essay on "Black Holes in String Theory" which I presented as first degree in physics thesis in my University. At present, I am writing my thesis for get the Master Degree in Physics on Renormalization Group Flow within Grand Unification Theories within Extra Dimensions, wich I will get by January 2003 y then I will start my PhD's work on topics related with high energy physics.

I am working on Higgs production simulations, by Pythia. I have performed a method to determine the parity of a Higgs boson via the angular distributions of decay and production.

I am a PhD. Student in DESY working on triple-gauge-boson coupling measurements at the future TESLA linear collider using transversely polarized beams. The study is focused on the analysis of the semi-leptonic decay channel for W-pair production in e$^+$e$^-$ annihilation using transversely polarized beams with $\sqrt{s}=500\;GeV$. For transverse polarization in both beams a dependence on the azimuthal angle $\phi$ for the cross section should be observed. In particular, sensitivity to CP-violating couplings is expected. A polarization of 80% for the e$^-$ beam and 60% for the e$^+$ beam is considered for the analysis.

For my Ph.D. thesis I am working on the BaBar experiment at SLAC. This is an experiment built to measure CP violation in the B sector. While on my long term attachment to BaBar. I have been heavily involved in producing a calibration correction for the front end electronics of the electromagnetic calorimeter.
I have recently started an analysis of the charmless decay B-> rho pi, which is a background to the charmless 3 body mode B-> 3pi, used in the extraction of the CP mixing parameter sin2alpha. Before this I was involved in a measurement of the decay B+ -> chic1 K+

For my PhD thesis I am working on LHCb, one of the experiment which will be constructed on the LHC proton collider at CERN. LHCb will study the the CP violation in the B0 system. I have to simulate the MWPC for the muon detector and the trigger for decays containing muons in the final state. On the hardware side I'm working on the construction, test and development of chamber prototype. The analysis of the testbeam of our prototypes showed good performances, as expected from the simulations.

I am beginning my Ph.D program and therefore I am starting my research activity. During the last six months I have studied the so called two Higgs doublet model type III (2HDM-III). It is a model where flavor changing neutral currents appear naturally, it means that the 2HDM-III in someway is more general than 2HDM-II, that has been extensively studied due to its appearence in the Susy version of the standard model. Our purpose in the model type III is to study the phenomenology of the Higgs sector, specifically the width decays of the Higgs bosons (5 in the model type III) and their branching fractions, and try to find some bounds on this sector comming from experimental studies. I should mention that all the experimental analysis have been done in the context of the 2HDM-II. Thus, I am going to use parametrizations of the 2HDM-III in order to compare with the 2HDM-III analisys.
