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...
متن کاملHadron 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 ...
متن کاملNon-relativistic Effective Theory for Quarkonium Production in Hadron Collisions
I review recent progress in understanding inclusive quarkonium production in hadron collisions. The rst part focuses on non-relativistic QCD as an e ective theory. I discuss its di erences from and similarities with e ective theories describing bound states of a single heavy quark, as far as matching calculations beyond tree-level and power counting are concerned. The second part summarizes pre...
متن کاملObservation of Exclusive Di-Photon Production in Hadron-Hadron Collisions
We present the first observation and cross section measurement of exclusive photon pair production in proton-antiproton collisions at √ s = 1.96 TeV taken by the Run II Collider Detector at Fer-milab. We select events with two electromagnetic showers, each with transverse energy E T > 2.5 GeV and pseudorapidity |η| < 1.0, with no other particles detected in −7.4 < η < +7.4. The two showers have...
متن کاملTHERMAL HADRON PRODUCTION IN Si-Au COLLISIONS
The most abundantly produced hadron species in Si−Au collisions at the BNL-AGS (nucleons, pions, kaons, antikaons and hyperons) are shown to be in accord with emission from a thermal resonance gas source of temperature T ≃ 110 MeV and baryochemical potential μB ≃ 540 MeV, corresponding to about 1/3 standard nuclear density. Our analysis takes the isopin asymmetry of the initial state fully into...
