Title: Prompt neutrinos and intrinsic charm at SHiP

Abstract

We present a new evaluation of the far-forward neutrino plus antineutrino flux and number of events from charm hadron decays in a 400 GeV proton beam dump experiment like the Search for Hidden Particles (SHiP). Using next-to-leading order perturbative QCD and a model for intrinsic charm, we include intrinsic transverse momentum effects and other kinematic angular corrections. We compare this flux to a far-forward flux evaluated with next-to-leading order perturbative QCD, without intrinsic transverse momentum, that used the angular distribution of charm quarks rather than the neutrinos from their decays. The tau neutrino plus antineutrino number of events in the perturbative QCD evaluation is reduced by a factor of about three when intrinsic transverse momentum and the full decay kinematics are included. We show that intrinsic charm contributions can significantly enhance the number of events from neutrinos from charm hadron decays. Measurements of the number of events from tau neutrino plus antineutrino interactions and of the muon charge asymmetry as a function of energy can be used to constrain intrinsic charm models.

Far-forward neutrinos at the Large Hadron Collider

Journal Article Bai, Weidong ; Diwan, Milind ; Garzelli, Maria Vittoria ; ... - Journal of High Energy Physics (Online)

We present a new calculation of the energy distribution of high-energy neutrinos from the decay of charm and bottom hadrons produced at the Large Hadron Collider (LHC). In the kinematical region of very forward rapidities, heavy-flavor production and decay is a source of tau neutrinos that leads to thousands of charged-current tau neutrino events in a 1 m long, 1 m radius lead neutrino detector at a distance of 480 m from the interaction region. In our computation, next-to-leading order QCD radiative corrections are accounted for in the production cross-sections. Non-perturbative intrinsic-kT effects are approximated by a simple phenomenological modelmore »« less

New Perspectives for QCD Physics at the LHC

Journal Article Brodsky, S. J. - AIP Conference Proceedings

I review a number of topics where conventional wisdom relevant to hadron physics at the LHC has been challenged. For example, the initial–state and final–state interactions of the quarks and gluons entering perturbative QCD hard–scattering subprocesses lead to the breakdown of traditional concepts of factorization and universality for transverse–momentum–dependent observables at leading twist. The soft–gluon rescattering effects, which are associated with the Wilson line of the propagating partons, also lead to Bjorken–scaling single–spin asymmetries, diffractive deep inelastic scattering, the breakdown of the Lam–Tung leading–twist relation in Drell–Yan reactions, as well as nuclear shadowing.

Measurement of single muons at forward rapidity in p+p collisions at {radical}(s)=200 GeV and implications for charm production

Journal Article Adler, S S ; Aidala, C ; Aronson, S H ; ... - Physical Review. D, Particles Fields

Muon production at forward rapidity (1.5{<=}|{eta}|{<=}1.8) has been measured by the PHENIX experiment over the transverse momentum range 1{<=}p{sub T}{<=}3 GeV/c in {radical}(s)=200 GeV p+p collisions at the Relativistic Heavy Ion Collider. After statistically subtracting contributions from light hadron decays an excess remains which is attributed to the semileptonic decays of hadrons carrying heavy flavor, i.e. charm quarks or, at high p{sub T}, bottom quarks. The resulting muon spectrum from heavy flavor decays is compared to PYTHIA and a next-to-leading-order perturbative QCD calculation. PYTHIA is used to determine the charm quark spectrum that would produce the observed muon excess. Themore »« less
