Hadron Production in Hadron-Hadron and Lepton-Hadron Collisions

We review a recent global analysis of inclusive single-charged-hadron production in high-energy colliding-beam experiments, which is performed at nextto-leading order (NLO) in the parton model of quantum chromodynamics endowed with nonperturbative fragmentation functions (FFs). Comparisons of pp data from CERN SppS and the Fermilab Tevatron and γp data from DESY HERA with the corresponding NLO ...

Resonant Slepton Production in Hadron–Hadron Collisions

We consider the resonant production of sleptons via 6Rp in hadron–hadron collisions followed by supersymmetric gauge decays of the sleptons. We look at decay modes which lead to the production of a like-sign dilepton pair. The dominant production mechanism giving this signature is the resonant production of a charged slepton followed by a decay to a charged lepton and a neutralino which then de...

Charm Hadron Production Fractions

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...

Universality in Hadron Production in Electron- Positron, Lepton-hadron and Hadron-hadron Reactions

Universality says that the mechanisms of hadron production are the same in all high-energy processes in which most of the final state hadrons arise from hard or semi-hard scattering of partons. Differences in the detailed composition of the final states are assumed to be due to differences in the flavours and configurations of the initial partons. Perturbative quantum chromodynamics (pQCD) has ...
