Abstract

The production of excited charm, D(1)(2420)(0) and D(2)*(2460)(0), and charm-strange, D(s1)(2536)(+/-), mesons in ep collisions was measured with the ZEUS detector at HERA using an integrated luminosity of 126 pb(-1). Masses, widths and helicity parameters were determined. The measured yields were converted to the rates of c quarks hadronising as a given excited charm meson and to the ratios of the dominant D(2)*(2460)(0) and D(s1)(2536)(+/-), branching fractions. A search for the radially excited charm meson, D*'(2640)(+/-), was also performed. The results are compared with those measured previously and with theoretical expectations.
