An overview of recent high-pT hadron and photon measurements at RHIC is presented with a focus on the evolution of hadron/photon production from intermediate pT (. 5 GeV/c) to high pT (> 10 GeV/c). Addressed topics include single high-pT hadron production, azimuthal anisotropy of π production, di-jet modification at intermediate pT and inclusive photon-hadron correlations. The understanding of ...

Hadron production is a key ingredient in many aspects of neutrino physics. Precise prediction of atmospheric neutrino fluxes, characterization of accelerator neutrino beams, quantification of pion production and capture for neutrino factory designs, all of these would profit of highstatistics, high-precision hadron production measurements. In addition, such data is needed for the calibration of...

Hadron production in single and central diffraction dissociation is studied in a model which includes soft hadron interaction as controlled by a supercritical pomeron parametrization and hard diffraction. Hard diffraction is described using leading-order QCD matrix elements together with the parton distributions for the proton, the less well known photon parton densities and a conjectured parto...

The world average values for the probabilities that a charm quark fragments into D and D s have been calculated to be f(c → D) = 0.235± 0.007 (±0.007) and f(c → D s ) = 0.101± 0.009 (±0.025), respectively. The average values for D, D and Λ c have been also calculated. [email protected] On leave from Moscow State University, supported by GIF, contract I-0444-176.07/95 Introduction The probab...
