Abstract:
We report new measurements of the cross sections for the production of DD final states at the ψ(3770) resonance. Our data sample consists of an integrated luminosity of 2.93 fb-1 of e+e- annihilation data produced by the BEPCⅡ collider and collected ...

Abstract:
The mass spectra of charmonium are investigated using a Coulomb plus linear (Cornell) potential. Gaussian wave functions in position space as well as in momentum space are employed to calculate the expectation values of potential and kinetic energy r...

We calculate the next-to-leading-order cross section for the inclusive production of Λb baryons in m pp collisions in the general-mass variable-flavor-number scheme. We use realistic evolved non-perturbative fragmentation functions obtained from fits...

The dissociation temperatures of quarkonium states in a thermal medium are obtained in the framework of the quark model with the help of the Gaussian Expansion Method (GEM). This is the first time this method has been applied to the dissociation prob...

Abstract:
The DArk Matter Particle Explorer (DAMPE) has observed a tentative peak at E～1.4 TeV in the cosmic-ray electron spectrum. In this paper, we interpret this excess in the scotogenic type-II seesaw model. This model extends the canonical type-II seesaw ...

We present a detailed study on the properties of the free energy density at high temperature by applying the principle of maximum conformality (PMC) scale-setting method within effective field theory. The PMC utilizes the renormalization group equati...

Abstract:
Reconsideration of the T-duality of the open string allows us to introduce some geometric features in non-geometric theories. First, we have found what symmetry is T-dual to the local gauge transformations. It includes transformations of background f...

Abstract:
Within the framework of the perturbative QCD approach, we calculate the time-like B_cm Bc(Bc*) form factors F(Q2) and A2(Q2). We include relativistic corrections and QCD corrections, either of which can give about 20% correction to the leading-order ...

We investigate the resonant production of color octet muons in order to explore the discovery potential of Future Circular Collider (FCC)-based μp colliders. It is shown that the search potentials of μp colliders essentially surpass the potential of ...

We examine the structural properties and half-life decay of Ra isotopes within the axially deformed Relativistic Mean-Field (RMF) theory with NL3 force parameters. We work out the binding energy (BE), RMS radii, two-neutron separation energies (S2n),...

Abstract:
We propose a novel method to search for the chiral magnetic effect (CME) in heavy ion collisions. We argue that the relative strength of the magnetic field (mainly from spectator protons and responsible for the CME) with respect to the reaction plane...

Abstract:
The influence of σ* and φ on the proto-neutron star (PNS) PSR J0348+0432 is described by the relativistic mean field theory (RMFT) through choosing effective coupling constants. We use an entropy per baryon S=1 to describe the thermal effects on PSR ...
