Strong interaction is believed to be described by a theory called Quantum Chromodynamics(QCD),an important sector of the Standard Model(SM)of particle physics.QCD is a strange and charming theory,just like the two nam...
First evidence of a structure in the J/ψΛinvariant mass distribution is obtained from an amplitude analysis of■b^(-)J/ψΛK^(-)decays.The observed structure is consistent with being due to a charmonium pentaquark w...

The spectroscopic parameters and decay channels of the axial-vector tetraquark Tho(in what follows,TAV)are explored using the quantum chromodynamics(QCD)sum rule method.The mass and coupling of this state are calculat...

Using proton-proton collision data at centre-of-mass energies of and 13 TeV recorded by the LHCb experiment at the Large Hadron Collider,corresponding to an integrated luminosity of 9 fb-1,the invariant mass spectrum ...

I discuss the production mechanism of hidden-flavored hadrons at high energy. Using e+e-collisions and light-meson pair production in high energy exclusive processes, I demonstrate that hidden quark pairs do not nece...
We live in the Age of Extinctions-the call for naming our time"Anthropocene"is no more than hubris and escapism from this colossal sin.Although the6thmass extinction has possibly already started(Barnosky et al.,201...

: The cross sections of e+e-→π+π-hc at center-of-mass energies from 3.90 to 4.42 GeV were measured by the BESIII and the CLEO-c experiments. Resonant structures are evident in the e+e-→π+π-hc line shape. Th...
We discuss recent progress in extracting the excited meson spectrum and radiative transition form factors from lattice QCD.We mention results in the charmonium sector,including the first lattice QCD calculation of rad...
An understanding of the confinement mechanism in QCD requires a detailed mapping of the spectrum of hybrid mesons.Understanding confinement means understanding the role of gluons and it is in hybrid mesons that the gl...
