Abstract

The inclusive production cross sections of the strange vector mesons K*, K, and φ have been measured in interactions of 920 GeV protons with C, Ti, and W targets with the HERA-B detector at the HERA storage ring. Differential cross sections as a function of rapidity and transverse momentum have been measured in the central rapidity region and for transverse momenta up to p = 3.5 GeV/c. The atomic number dependence is parametrised as σ=σ *A, where σ is the proton-nucleon cross section. Within the phase space accessible, α(K )=0.86±0.03, α(K*)=0. 87±0.03, and α(φ)=0.96±0.02. The total proton-nucleon cross sections, determined by extrapolating the differential measurements to full phase space, are σ=(5.06±0.54) ∈mb, σ=(4.02±0.45)∈mb, and σ=(1.17±0.11)∈mb. For all resonances the Cronin effect is observed; compared to the measurements of Cronin et al. for K mesons, the measured values of α for φ mesons coincide with those of K mesons for all transverse momenta, while the enhancement for K/K mesons is smaller. © Springer-Verlag Berlin Heidelberg 2007.
