An enhancement near the ωp threshold has been observed with a mass of 1820 MeV and a width of about 120 MeV from the reaction π-p→π-ωp at 4.5, 6, and 14 GeV/c. There is no strong evidence for πN or ρN decay modes. We examine spin and parity a

Observation of a Dip Due toI=0t-Channel Exchange in the ReactionπN→A2Nat 4.5 and 6 GeV/c
Autor: Kwan-Wu Lai, I. Stumer, Howard Gordon, M. Habibi
Publikováno v: Physical Review Letters. 33:603-606
In the reaction ${\ensuremath{\pi}}^{\ensuremath{-}}p\ensuremath{\rightarrow}{{A}_{2}}^{\ensuremath{-}}p$, we observe a dip in the differential cross section at $t\ensuremath{\approx}1.2$ Ge${\mathrm{V}}^{2}$. Analysis in terms of $t$-channel contrib

Meson Structure Functions from High-Transverse-Momentum Hadron Interactions
Autor: Kwan-Wu Lai, Robert L. Thews
Publikováno v: Physical Review Letters. 44:1729-1733
Data on large--transverse-momentum ..pi../sup 0/ production by proton, pion, and kaon beams is used to extract the large-x behavior of meson structure functions. Good agreement is found with the proton and pion quark distribution functions obtained f

Study of Quark Structure Functions
Autor: E. Flaminio, F. T. Dao, W. Metcalf, Ling-Lie Wang, Kwan-Wu Lai
Publikováno v: Physical Review Letters. 39:1388-1391
The quark structure functions of the proton are determined through a combined analysis of the reactions pN ..-->.. ll-barX and eN ..-->.. eX. The valence-quark structure function of the pion is also given by analyzing the ..pi..N ..-->.. ..mu mu..-ba

Study of Threshold Enhancements inρ0π−andf0π−Systems from the Reactionπ−p→pπ+π−π−AT 6 GeV/c
Autor: Kwan Wu Lai, Uri Karshon, W. H. Sims, J. Michael Scarr, David J. Crennell
Publikováno v: Physical Review Letters. 24:781-785
We have observed, in a high-statistics experiment, well-defined threshold enhancements in the ${\ensuremath{\rho}}^{0}{\ensuremath{\pi}}^{\ensuremath{-}}$ and ${f}^{0}{\ensuremath{\pi}}^{\ensuremath{-}}$ systems at 1120 and 1645 MeV, respectively. We
