Measurement of unpolarized semi-inclusive pi+ electroproduction off the proton

CLAS Collaboration, M. Osipenko, M. Ripani +3

Semi-inclusive pi+ electroproduction on protons has been measured with the CLAS detector at Jefferson Lab. The measurement was performed on a liquid-hydrogen target using a 5.75 Ge…

Electroexcitation of the Roper resonance for 1.7 < Q2 < 4.5 GeV2 in ep -> enpi+

I. G. Aznauryan, V. D. Burkert, W. Kim +2

The helicity amplitudes of the electroexcitation of the Roper resonance are extracted for 1.7 < Q2 < 4.5 GeV2 from recent high precision JLab-CLAS cross section and longitudinally…

Light Vector Mesons in the Nuclear Medium

M. H. Wood, R. Nasseripour, D. P. Weygand +5

The light vector mesons ( $ρ$ , $ω$ , and $ϕ$ ) were produced in deuterium, carbon, titanium, and iron targets in a search for possible in-medium modifications to the properties of the…

Cross sections and beam asymmetries for $\vev{e}p \to enπ^+$ in the nucleon resonance region for $1.7 \leq Q^{2} \leq 4.5 (G e V)^{2}$

K. Park, V. D. Burkert, W. Kim +1

The exclusive electroproduction process $e p \to e^{'} n π^{+}$ was measured in the range of the photon virtuality $Q^{2} = 1.7 - 4.5 Ge V^{2}$ , and the invariant mass range…

First measurement of coherent $ϕ$ -meson photoproduction on deuteron at low energies

CLAS collaboration, T. Mibe, H. Gao +4

The cross section and decay angular distributions for the coherent ϕmeson photoproduction on the deuteron have been measured for the first time up to a squared four-momentum transf…

Cascade production in the reactions gamma p --> K+ K+ (X) and gamma p --> K^+ K^+ pi- (X)

L. Guo, D. P. Weygand, M. Battaglieri +3

Photoproduction of the cascade resonances has been investigated in the reactions $γ p \to K^{+} K^{+} (X)$ and $γ p \to K^{+} K^{+} π^{-} (X)$ . The mass split of the $Ξ$ doublet is measured to…
