Resolving the universality and polarization puzzles in hadroproduction
An-Ping Chen, Jun Guo, Yan-Qing Ma
Prompt hadroproduction poses two related puzzles: fixed-order hadronic and analyses give incompatible constraints on the same color-octet (CO) long-distance matrix e…
Shedding Light on Hadronization by Quarkonium Energy Correlator
An-Ping Chen, Xiaohui Liu, Yan-Qing Ma
We propose to measure the energy correlator in quarkonium production, which tracks the energy deposited in the calorimeter -angular distance away from the identified quarkonium.…
Resolving negative cross section of quarkonium hadroproduction using soft gluon factorization
An-Ping Chen, Yan-Qing Ma, Ce Meng
It was found that, using nonrelativistic QCD factorization, the predicted hadroproduction cross section at large can be negative. The negative cross sections origina…
Color-octet contributions for inclusive production at B factories in soft gluon factorization
An-Ping Chen, Xiao-Bo Jin, Yan-Qing Ma +1
We have studied color-octet contributions for inclusive production at B factories, i.e., , using the soft g…
A short theoretical review of charmonium production
An-Ping Chen, Yan-Qing Ma, Hong Zhang
In this paper, we review the current status of the phenomenological study of quarkonium production in high energy collisions. After a brief introduction of several important models…
Fragmentation function of in soft gluon factorization and threshold resummation
An-Ping Chen, Xiao-Bo Jin, Yan-Qing Ma +1
We study the fragmentation function of the gluon to color-octet heavy quark-antiquark pair using the soft gluon factorization (SGF) approach, which expresses the fragmentat…
