The coexistence of neutron-neutron (n-n),proton-proton (p-p),and neutron-proton (n-p) pairings is in-vestigated by adopting an effective density-dependent contact pairing potential.These three types of pairings can co-exist only if the n-p pairing is stronger than the n-n and p-p pairings for the isospin asymmetric nuclear matter.In ad-dition,the existence of n-n and p-p pairs might enhance n-p pairings in asymmetric nuclear matter when the n-p pair-ing strength is significantly stronger than the n-n and p-p ones.Conversely,the n-p pairing is reduced by the n-n and p-p pairs when the n-p pairing interaction approaches n-n and p-p pairings.

In this work,we calculate the sub-leading power contributions to radiative leptonic D → γlv decay.For the first time,we provide the analytic expressions of next-to-leading power contributions and the error estimation as-sociated with the power expansion o
We studied the effects of centrality fluctuation and deuteron formation on the cumulant (Cn) and correla-tion functions (κn) of protons up to the sixth order in the most central (b＜ 3 fm) Au+Au collisions at √SNN =3 GeV in a microscopic transport model (J
This paper presents perturbative QCD predictions of the electron charge asymmetry for inclusive W± + X → e±v + X production in proton-proton (pp) collisions.Perturbative QCD calculations are performed at next-to-next-to-leading order (NNLO) accuracy using
Anomalies in decays induced by b → ce-(v)e(e =e,μ,τ) transitions may imply lepton flavor universality violations,which raises questions on such phenomena in the D decays induced by c → (s,d)e+ve transitions.Cur-rent measurements of the pure leptonic and s
First-principle calculations based on the density functional theory (DFT) method are adopted to investig-ate the influence of a strong electric field on the 7Be half-life.Accordingly,electronic structures of Be and BeO are examined in the presence of a ho

Cosmic-ray (CR) anti-nuclei are often considered important observables for indirect dark matter (DM)detection at low kinetic energies,below GeV per nucleon.Since the primary CR fluxes drop quickly towards high energies,the secondary anti-nuclei in CR are
We extend the hotspot model to include the virtuality dependence and use it to study the exclusive and dissociative J/ψ production combined with the dipole amplitude in the target rapidity representation.We determ-ined that virtuality takes effect on a nu
