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…
Measurement of the N to Delta(1232) Transition at High Momentum Transfer by pi0 Electroproduction
M. Ungaro, P. Stoler, I. Aznauryan +4
We report a new measurement of the exclusive electroproduction reaction gamma* p -> pi0 p to explore the evolution from soft non-perturbative physics to hard processes via the Q2 d…
Precision Measurements of the Timelike Electromagnetic Form Factors of the Pion, Kaon, and Proton
P. Zweber
Using 20.7 pb^-1 of e+e- annihilation data taken at sqrt{s} = 3.671 GeV with the CLEO-c detector, precision measurements of the electromagnetic form factors of the charged pion, ch…
Experimental Limits on Weak Annihilation Contributions to b -->u ell nu Decay
J. L Rosner, CLEO Collaboration
We present the first experimental limits on high-q^2 contributions to charmless semileptonic B decays of the form expected from the Weak Annihilation (WA) decay mechanism. Such con…
Measurement of the Direct Photon Momentum Spectrum in Upsilon(1S), Upsilon(2S), and Upsilon(3S) Decays
D. Besson, CLEO Collaboration
Using data taken with the CLEO III detector at the Cornell Electron Storage Ring, we have investigated the direct photon spectrum in the decays Upsilon(1S) -> gggamma, Upsilon(2S)…
Experimental Study of chi_b(2P) --> pi pi chi_b(1P)
C. Cawlfield, CLEO Collaboration
We have searched for the di-pion transition chi_b(2P) -> pi pi chi_b(1P) in the CLEO III sample of Upsilon(3S) decays in the exclusive decay chain: Upsilon(3S) -> gamma chi_b(2P),…
