Light-Gravitino Production at Hadron Colliders
We consider the production of gravitinos (G̃) in association with gluinos (g̃) or squarks (q̃) at hadron colliders, including the three main sub-processes: qq̄ → g̃G̃, qg → q̃G̃, and gg → g̃G̃. These channels become enhanced to the point of being observable for sufficiently light gravitino masses (m G̃ < 10−4 eV), as motivated by some supersymmetric explanations of the CDF eeγγ +ET,miss event. The charact...
متن کاملTheoretical Aspects of Inclusive Light-Hadron Production
We summarize the key results of a recent global analysis of inclusive singlecharged-hadron production in high-energy colliding-beam experiments. In the framework of the parton model of quantum chromodynamics at next-to-leading order (NLO), fragmentation functions (FFs) for charged pions, charged kaons, and (anti) protons are extracted from experimental data of e+e− annihilation at the Z-boson r...
متن کاملIdentified Hadron Production and Light Quark Fragmentation in
We have measured the differential cross sections for the production of π, K, K, K, φ, p, Λ and their corresponding antiparticles in separate samples of flavor-tagged Z → light-flavor (uū, dd̄, or ss̄), Z → cc̄ and Z → bb̄ events. Clear flavor dependences are observed, and the results are compared with the predictions of three fragmentation models. We have also performed a direct measurement of As, ...
متن کاملProduction of light stabilized radion at high energy hadron colliders
In this paper we derive the coupling of light stabilized radions to gluons in the Randall-Sundrum model and use it to compute the radion production cross section at hadron colliders by gluon fusion. Using the effective Lagrangian for higgs coupling to gluons in the heavy quark limit we then show analytically that the radion production cross section through gluon fusion would exceed the higgs pr...
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 ...
