The Role of the D13 (1520) Resonance in eta Electroproduction
R. M. Davidson, N. Mathur, N. C. Mukhopadhyay
We investigate the electroproduction of eta mesons below a center of momentum energy of 1.6 GeV, with particular emphasis on the roles of the N*(1535) and N*(1520) resonances. Usin…
Proton Spin Content From Lattice QCD
Nilmani Mathur, S. J. Dong, K. F. Liu +1
We calculate the form factor of the quark energy momentum tensor and thereby extract the quark orbital angular momentum of the nucleon. The calculation is done on a quenched $16^3…
Electroproduction of the Delta Resonance at High Momentum Transfer
V. V. Frolov et al
We studied the electroproduction of the Delta(1232) resonance via the reaction p(e,e'p)\pi0 at four-momentum transfers Qsq = 2.8 and 4.0 GeV^2. This is the highest Qsq for which ex…
Parity-Violating Excitation of the Δ(1232): Hadron Structure and New Physics
N. C. Mukhopadhyay, M. J. Ramsey-Musolf, S. J Pollock +2
We consider prospects for studying the parity-violating (PV) electroweak excitation of the Δ(1232) resonance with polarized electron scattering. Given present knowledge of Standard…
Mainz "measurement" of the ratio in the transition
R. M. Davidson, N. C. Mukhopadhyay
We comment on the recent Mainz "measurement" (PRL78 (1997) 606) of the ratio in the electromagnetic transition. Analyzing the Mainz data using an effective Lagrangian…
A Precise Determination of the Pion-Nuclear Coupling Parameter from Weak Processes in ^3He
Nimai C. Mukhopadhyay, K. Junker
We utilize precise weak interaction experiments on atomic muon capture and beta decay in the A = 3 nuclei, and take into account the effects of nuclear "anomalous thresholds" to ex…
