Inspired by the recent discovery of the X(6900) meson in the LHCb experiment,we investigate the in-clusive production rate of the C-odd fully-charmed tetraquarks associated with light hadrons at the B factory within the nonrelativistic QCD (NRQCD) factorization framework.The short-distance coefficient is computed at the low-est order of velocity and αs.Employing two different kinds of phenomenological models to approximately estimate the long-distance NRQCD matrix element,we predict the rate for the inclusive production of the 1+-T4c state and discuss the observation prospect of the Belle 2 experiment.

Excited states in the odd-A nucleus 71Ga have been studied via the 70Zn(7Li,α2n)71Ga fusion-evapora-tion reaction with incident beam energies of 30 and 35 MeV.The level scheme is established up to spin Iπ=(29/2+)and an excitation energy~6.6 MeV.A previous
The large values and constituent-quark-number scaling of the elliptic flow of low-pT D mesons imply that charm quarks,initially produced through hard processes,might be partially thermalized through strong interac-tions with quark-gluon plasma (QGP) in hi
A perturbative method of computing the total travel time of both null and lightlike rays in arbitrary static spherically symmetric spacetimes in the weak field limit is proposed.The resultant total time takes a quasi-series form of the impact parameter.Th
Considering a grand canonical ensemble,we study the phase structures and transitions of RN black holes surrounded by quintessence dark energy on two different boundary conditions,namely AdS space and a Dirichlet wall.For AdS space,under the condition of f
The isoscaling parameters αeval in the fiissioning systems,i.e.,those extracted from the Evaluated Nucle-ar Data Library(ENDF/B-Ⅷ.0)and the Joint Evaluated Fission and Fusion File(JEFF-3.3),show an obvious dif-ference from simple statistic model predictio
The moments and moment products of conserved charges are believed to be sensitive to critical fluctu-ations,which have been adopted in determining the QCD critical point.Using a dynamical multiphase transport model,we reproduce the centrality and energy d
We continue our endeavor to investigate lepton number violating (LNV) processes at low energies in the framework of effective field theory (EFT).In this work we study the LNV tau decays r+ → l-P+iP+j,where l =e,μ and P+i,j denote the lowest-lying charged
The first search for the doubly heavy Ω0bc baryon and a search for the Ξ0bc baryon are performed using pp collision data collected via the LHCb experiment from 2016 to 2018 at a centre-of-mass energy of 13 TeV,cor-responding to an integrated luminosity of
The self-consistent mean field approximation of the two-flavor NJL model,with a free parameter α to reflect the competition between the “direct” channel and the “exchange” channel,is employed to study the QCD phase structure at finite isospin chemical pot
Combining the b → sμ+μ-anomaly and dark matter observables,we study the capability of the LHC to test dark matter,Z\',and a vector-like quark.We focus on a local U(1)Lμ-Lr model with a vector-like SU(2)L doublet quark Q and a complex singlet scalar whos
