Studies of D1*(2420) and D2*(2460) mesons at HERA II. — •Andrii Verbytskyi — ZEUS Experiment, DESY, Notkestr. 85, 22607 Hamburg, Germany
Studies of D meson properties provide important information about the internal structure of matter. One of such studies is the determination of D1*(2420) and D2*(2460) properties. The masses of these mesons are measured well enough, but some quantities like I, J, P, calculated from quark theory, need to be confirmed. Also, there is no precise data for the decay mode fractions and cross sections of these mesons. So measurement of these quantities will be valuable. The HERA II data taken by the ZEUS detector provide large statistics of D* decays in several modes with high reconstruction quality. Thus it should be possible to obtain high quality D1*(2420) and D2*(2460) signals for analysis. In this talk the first steps of this analysis are presented.
