For my Ph.D. thesis I am working on SVD, on the detector operating at IHEP accelerator at Protvino. I am performing analysis of the data collected by SVD on charm hardroproduction obtained in fixed target experiment at 70 Gev/c. |

I'm working on a design and doing some studies of the long scintillator counter with a precision timing for the TOF hodoscope, which will be used for the particle identification in the GlueX experiment at the Jefferson Lab. |

I am working now on data analysis of the charge kaon decay experiment performed at 70GEV IHEP accelerator using Tagged Neutrino Facility station (TNF). In total 300 million decays have been collected in the experiment. In particular my task is to choose the effective selection criteria for [K(+-)=>Pi0 e(+-) Nu Gamma] decays with BR~0.0001 to suppress the background. The final goal of my work is to search for T-violation in these decays. |

I started to work in the field of Experimental Particle Physics in the autumn 2001, when I joined The Particle Physics Group at University of Sofia. Under the supervision of Prof. Dr. Leandar Litov I was involved in the data analysis for NA48 experiment. The continuation of my work was connected with my stay at CERN for three months as a summer student last year. During this period an investigation of the decay Ks->pi0 mu+ mu- has been performed. An upper limit for its branching ratio was set for the first time using NA48 data recorded in 2001. Currently my aim is to improve this limit using the data recorded in year 2002 by NA48/1 experiment. Separately I was involved in the analysis of radiative kaon decays including simulation software development. |

My current research focuses on understanding the hadronization process in e+e- interactions, using Bose-Einstein interferometry as a tool to determine the size of the source of hadrons. The LEP data suggest that the radius of the volume from which identical bosons and fermions are emitted decreases with increasing masses of the particles. I participated in investigations aimed at understanding of the observed phenomenon within a model proposed by the Cracow theorists A. Bialas and K. Zalewski. I continue these studies working currently on another method of the correlation radius determination which is expected to give reduced systematic errors. This method allows to estimate values of the parameters characteristic for the area of hadronization from correlations studied in "simple" variables, such as polar and azimuthal angles and rapidity. By choosing variables like those we can eliminate the problem of constructing reference sample. Analysis of the difference between azimuthal angles of pipi and KK mesons allows to obtain values of R_transversal radius. |
