Ultra-high-energy -ray imprints from PeV particles accelerated by supernova remnants
Zhen Cao, F. Aharonian, Y. X. Bai +320
The quest for the origin of cosmic ray (CRs) is a fundamental issue in astrophysics. Shocks of supernova remnants (SNRs) have been considered as the dominant contributors to Galact…
Productions of and its SU(3)-flavor symmetry and heavy quark spin symmetry partners in decays
Yi Zhang, Ming-Zhu Liu, Li-Sheng Geng
Inspired by the observation of the doubly charmed tetraquark state at collisions in the inclusive processes, we systematically investigate the production of doubly ch…
helicity form factors within QCD light-cone sum rules
Yi Zhang, Wei Cheng, Jia-Wei Zhang +3
In this paper, we investigate the helicity form factors (HFFs) of the -meson decay into a scalar meson with a mass larger than 1~GeV, {\it i.e.,} , $B_{(s…
puzzle in semi-leptonic decays revisited
Shuang-Yi Li, Jie Xu, Rui-Xiang Shi +2
Inspired by the newly reported differential decay rates by the Belle and Belle II Collaborations, we revisit the puzzle in semi-leptonic…
