Rescattering Effect and Near Threshold Enhancement of System
G. Y. Chen, H. R. Dong, J. P. Ma
We study the observed enhancement of a system near the threshold in the process and . From early studies the enhancement can be exp…
Nonperturbative Corrections with Nonlocal Operators to Lifetime Ratios of Beauty Hadrons
J. P. Ma, Z. G. Si
The motion of spectator quarks in decay of a beauty hadron is a nonperturbative effect which can usually be neglected. We find that the motion in some decay channels, which contrib…
The Mass Effect in Quarkonium Decay
J. P. Ma
In the NRQCD factorization for productions and decays of a quakonium the difference between the quarkonium mass and the twice of the heavy quark mass is neglected at the leading or…
A Nonperturbative Study of Quarkonium Systems
J. P. Ma, B. H. J. McKellar
Using Nonrelativistic QCD on the lattice we studied the mass spectrum of quarkonium systems nonperturbatively for a range of the bar quark mass. We determined two products of the m…
