( 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 کاملUPDATE to E12-09-002; Charge Symmetry Violating Quark Distributions via Precise Measurement of π/π Ratios in Semi–inclusive Deep Inelastic Scattering
This experiment will use the SHMS and HMS in Hall C to measure electrons and charged pions in coincidence. In this case, the SHMS will be used as the electron arm, and the HMS as the hadron arm. The experiment will measure semi–inclusive production of charged pions at three different values of Q=4.0, 5.0, and 6.1 GeV at large x. A range of x and z values is required to fully constrain charge sy...

متن کامل( Proposal to Jefferson Lab PAC 30 ) Measurement of the Ratio R = σ L / σ T in Semi - Inclusive Deep - Inelastic Scattering July 6 , 2006
We propose to perform measurements of the ratio R = σ L /σ T of longitudinal to transverse cross sections in pion electroproduction. Our emphasis will be on measurements in the so-called semi-inclusive deep inelastic scattering region, with extensions into the exclusive region. Whereas inclusive scattering can not distinguish between the quark flavor, there is great promise in flavor decomposit...
متن کاملTransverse Momentum Dependence of Semi - Inclusive Pion and Kaon Production July 5 , 2011
1 Executive Summary E12-09-017 plans to make precise measurements of cross sections of semi-inclusive charged-pion (π ±) electroproduction at deep inelastic scattering kinematics and low transverse momentum (P h⊥) from hydrogen and deuterium targets. The experiment will simultaneously, albeit with a factor of ten lower rates, accumulate charged-kaon (K ±) cross secion measurements, and obtain h...
