-Production at Photon-Photon Colliders as a Probe of the Color Octet Mechanism
J. P. Ma, B. H. J. McKellar, C. B. Paranavitane
We study production at photon-photon colliders, which can be realised with Compton scaterring of laser photons at colliders. We find that the production rate through…
Perturbative Prediction for Parton Fragmentation into Heavy Hadron
J. P. Ma
By expanding functions of parton fragmentation into a heavy hadron in the inverse of the heavy quark mass we attempt to factorize them into perturbative- and nonperturbative…
Higher Twist Effect in Inclusive Quarkonium Photoproduction
J. P. Ma
We analyze higher twist effect in photoproduction of quarkonium, where the quarkonium is a spin-triplet, S-wave state. We find that the nonperturbative effect of next-to-leading tw…
The Mass Spectrum of Light and Heavy Hadrons from Improved Lattice Actions
J. P. Ma, B. H. J. McKellar
We use improved lattice actions for glue, light quarks and heavy quarks for which we use lattice NRQCD to compute hadron masses. Our results are in good agreement with experiment,…
