CC and NC Pion Production

Baryon-Pion Couplings from Large-Nc QCD

We derive a set of consistency conditions for the pion-baryon coupling constants in the large-Nc limit of QCD. The consistency conditions have a unique solution which are precisely the values for the pion-baryon coupling constants in the Skyrme model. We also prove that non-relativistic SU(2Nf ) spin-flavor symmetry (where Nf is the number of light flavors) is a symmetry of the baryon-pion coup...

A concise [C+NC+CC] coupling-enabled synthesis of kaitocephalin.

A 15-step synthesis of the iGluR antagonist kaitocephalin from aspartic acid is reported. The linchpin pyrrolidine ring of the target molecule is efficiently assembled with in a single operation via an asymmetric [C+NC+CC] reaction.

Heavy Quark Production in CC and NC DIS and The Structure of Real and Virtual Photons in NLO QCD

Double Pion Production Reactions

We report on reactions producing two pions induced by real and virtual photons or nucleons. The role of different resonances in these reactions is emphasized. Novel results on coherent 2π photoproduction in nuclei are also reported. 1 Double pion photoproduction on the nucleon. The γN → π+π−N reaction is attracting attentions of both theoretical and experimental groups and is bound to play a si...

BOSE-EINSTEIN CORRELATIONS IN PION PRODUCTION AT TRISTAN

Measurement of Bose-Einstein correlations in the production of like-signed pion pairs has been made with the AMY detector at TRISTAN. An event sample of 10120 hadronic events with ranging between 50 to 61 GeV was used. These measurements indicate a strength of the enhancement of ? = 0.61M.07, with a typical correlation size of Ro = 1.16±.08 fm. This value of ? is consistent with measurem...
