Light quark fragmentation into S-wave fully charmed tetraquark
Xiao-Wei Bai, Yingsheng Huang, Wen-Long Sang
We compute the fragmentation function of a light quark into S-wave fully-charmed tetraquarks () within the nonrelativistic QCD (NRQCD) framework, at leading order in $α_{s}…

Producing Fully-Charmed Tetraquarks via Charm Quark Fragmentation in Colliders
Xiao-Wei Bai, Feng Feng, Chang-Man Gan +3
Within the framework of nonrelativistic QCD (NRQCD), we calculate the fragmentation function for a charm quark into an -wave fully-charmed tetraquark, denoted as . The c…

Two-Loop QCD Corrections to C even Bottomonium Exclusive Decays to Double
Yu-Dong Zhang, Xiao-Wei Bai, Feng Feng +2
In the framework of nonrelativistic QCD (NRQCD) factorization, we compute both the polarized and the unpolarized decay widths for the processes , accurate up…
