The inelastic scattering cross section for muons,μ-,with energies E =9-100 eV from the 229Th nuclei is calculated in the framework of the second order of the perturbation theory for quantum electrodynamics.The dom-inant contribution to the excitation of the low energy isomer 229mTh(3/2+,8.19 + 0.12 eV) originates from the E2 multipole.The excitation cross section reaches the value of 10-21 cm2 in the range E ≈ 10 eV.This value is four to five orders of magnitude larger than the electron excitation cross section and is sufficient for the efficient excitation of 229m Th on the muon beam at the next generation of muon colliders.

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
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) factori
We present a preliminary study of charge exchange heavy ion induced reactions based on the con-strained molecular dynamics(CoMD)model.The purpose is to test the capability of the model in predicting the oc-currence of single charge exchange(SCE)and double
The chiral phase transition and equation of state are studied within a novel self-consistent mean-field ap-proximation of the two-flavor Nambu-Jona-Lasinio model.In this newly developed model,modifications to the chemical μ and chiral chemical μ5 potentia
Three typical Pauli blocking algorithms in quantum molecular dynamics type models are investigated in the nuclear matter,the nucleus,and heavy ion collisions.In nuclear matter,the blocking ratios obtained with the three algorithms are underestimated by 13
Recently,the LHCb Collaboration reported their observation of the first two fully open-flavor tetraquark states named X0(2900) and X1 (2900) with unknown parity.Inspired by the report,we consider all the possible four-quark candidates for X(2900),which in
