The next-to-next-to-leading-order QCD corrections to at B factories
Cong Li, Wen-Long Sang, Hong-Fei Zhang
We investigate the processes and at B factories within the NRQCD factorization framework, computing the corresponding helicity amplitudes thr…
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…
Hadronic decay of exotic mesons consisting of four charm quarks
Hong-Fei Zhang, Xue-Mei Mo, Yu-Peng Yan
In 2020, a di- resonance centered at around 6.9 was discovered by the LHCb Collaboration, and was later confirmed by the ATLAS and CMS Collaborations. In additi…
Perturbative QCD Evidence for Spin-2 Particles in the Di- Resonances
Hong-Fei Zhang, Yan-Qing Ma, Wen-Long Sang
We extend the nonrelativistic QCD framework to explore the nature of the newly discovered di- resonances. Assuming them as either molecule-like states or tetraquarks, we calcu…
