( Resubmission of E 12 - 09 - 017 to Jefferson Lab PAC 37 ) Transverse Momentum Dependence of Semi - Inclusive Pion and Kaon Production December 1 , 2010
We propose to map the transverse momentum (Pt) dependence for semi-inclusive electroproduction of charged pions (π±) and, simultaneously albeit with a factor of ten lower rates, kaons (K±) from both proton and deuteron targets. The proposed measurements cover the range 0.2 < x < 0.5, 2 < Q < 5 GeV, 0.3 < z < 0.5, and Pt < 0.5 GeV. The Hall C HMS spectrometer and the projected SHMS with its firs...
متن کاملA CLAS Collaboration Proposal to PAC 37 Meson Spectroscopy with low Q 2 electron scattering in CLAS 12
Understanding quark and gluon confinement in Quantum Chromodynamics is one of the outstanding issues in physics. To this end, meson spectroscopy is a powerful tool to investigate how the QCD partons manifest themselves under the strong interaction at the energy scale of the nucleon mass (GeV). We propose a comprehensive study of the meson spectrum with precise determination of resonance masses ...
متن کاملStudy of the Short Range Properties of Nucleons at Q 2 ≤ 12 GeV 2 Using d ( e , e ’ p ) n With CLAS 12 A Proposal to PAC 30
We are proposing to search for two possible QCD phenomena, Point Like Configurations (PLC) in the proton wave function, and modification of (deeply bound) nucleons involved in Short Range Correlations. We will use the exclusive d(e, e′p)n reaction, which is the most understood nucleon knockout reaction. This search will be an extension of the CLAS e6 experiment, which found no evidence for PLC ...
متن کاملExclusive photoproduction of lepton pairs at LHC
Exclusive photoproduction of dileptons, γp → `+`− p, will be measured in ultraperipheral collisions at LHC. The mechanism where the lepton pair comes from a heavy timelike photon radiated from a quark interferes with the pure QED process γγ → `+`−. As an analog of deeply virtual Compton scattering, this timelike Compton scattering is a way to study generalized parton distributions in the nucleo...
متن کاملElastic vector meson production and DVCS at HERA
Recent results from the H1 and ZEUS experiments are reviewed. The cross sections of elastic photoand electroproduction of the vector mesons φ and J/ψ are measured as functions of Q2,W and t. The large statistics and the large coverage in t and W allow the determination of the effective Regge exchange trajectories, which are found to be different from the soft pomeron trajectory. Shrinkage is ob...
