Precise Measurement of pi+ -> e+ nu Branching Ratio
E. Frlež, L. P. Alonzi, V. A. Baranov +23
The PEN Collaboration is conducting a new measurement of the pi+ -> e+ nu branching ratio at the Paul Scherrer Institute, with the goal uncertainty of delta B/B(pie2)=5E-4 or lower…
Beam Spin Asymmetries in DVCS with CLAS at 4 .8 GeV
G. Gavalian
We report measurements of the beam spin asymmetry in Deeply Virtual Compton Scattering (DVCS) at an electron beam energy of 4.8 GeV using the CLAS detector at the Thomas Jefferson…
Probing Quark-Gluon Interactions with Transverse Polarized Scattering
K. Slifer, O. A. Rondon, A. Aghalaryan +69
We have extracted QCD matrix elements from our data on double polarized inelastic scattering of electrons on nuclei. We find the higher twist matrix element \tilde{d_2}, which aris…
A Precise Measurement of the Neutron Magnetic Form Factor GMn in the Few-GeV2 Region
J. Lachniet, A. Afanasev, H. Arenhövel +5
The neutron elastic magnetic form factor GMn has been extracted from quasielastic electron scattering data on deuterium with the CEBAF Large Acceptance Spectrometer (CLAS) at Jeffe…
Nab: Measurement Principles, Apparatus and Uncertainties
D. Pocanic, R. Alarcon, L. P. Alonzi +23
The Nab collaboration will perform a precise measurement of 'a', the electron-neutrino correlation parameter, and 'b', the Fierz interference term in neutron beta decay, in the Fun…
Electroproduction of p π^{+} π^{-} off protons at 0.2<Q^{2}<0.6 GeV^{2} and 1.3<W<1.57 GeV with CLAS
G. V. Fedotov, V. I. Mokeev, V. D. Burkert +5
This paper reports on the most comprehensive data set obtained on differential and fully integrated cross sections for the process . The data were collec…
