Abstract:
The existence of doubly heavy flavor baryons has not been well established experimentally so far. In this Letter we systematically investigate the weak decays of the doubly charmed baryons, Ξcc++ and Ξcc+, which should be helpful for experimental sea...

The Circular Electron-Positron Collider (CEPC) is a future Higgs factory proposed by the Chinese high energy physics community. It is planned to operate at a center-of-mass energy of 240-250 GeV and is expected to accumulate an integrated luminosity ...

A top quark mass measurement scheme near the tt production threshold in future e+e- colliders, e.g.the Circular Electron Positron Collider (CEPC), is simulated. A χ2 fitting method is adopted to determine the number of energy points to be taken and t...

Abstract:
We extract the mass spectrum of the triply heavy baryon Ωccb using the hypercentral constituent quark model. The first order correction is also added to the potential term of the Hamiltonian. The radial and orbital excited state masses are determined...

Abstract:
We generalize several well known quantum equations to a Tsallis' q-scenario, and provide a quantum version of some classical fields associated with them in the recent literature. We refer to the q-Schrödinger, q-Klein-Gordon, q-Dirac, and q-Proca equ...

In companion papers A. Addazi, Nuovo Cim. C, 38(1):21 (2015), A. Addazi, Z. Berezhiani, and Y. Kamyshkov, arXiv:1607.00348, we have discussed current bounds on a new super-light baryo-photon, associated with a U(1)B-L gauge, from current neutron-anti...

Abstract:
We study the maximally supersymmetric AdS backgrounds of matter-coupled N=3 gauged supergravity in four dimensions. We find that to admit supersymmetric AdS vacua, the gauge group can only be of the form G0×H⊂ SO(3,n) with G0=SO(3), SO(3,1) or SL(3,R...

The DD* interaction via a ρ or ω exchange is constructed within an extended hidden gauge symmetry approach, where the strange quark is replaced by the charm quark in the SU(3) flavor space. With this DD* interaction, a bound state slightly lower than...

Abstract:
The magnetic field plays a major role in searching for the chiral magnetic effect in relativistic heavy-ion collisions. If the lifetime of the magnetic field is too short, as predicted by simulations of the field in vacuum, the chiral magnetic effect...

We adopt the Nambu-Jona-Lasinio (NJL) model to study the crust-core transition properties in neutron stars (NSs). For a given momentum cutoff and symmetry energy of saturation density in the NJL model, decreasing the slope of the symmetry energy give...

The power index formula has been used to obtain the band head spin (I0) of all the superdeformed (SD) bands in Hg isotopes. A least squares fitting approach is used. The root mean square deviations between the determined and the observed transition e...

Abstract:
Experimentally observed superdeformed (SD) rotational bands in 36Ar and 40Ar are studied by the cranked shell model (CSM) with the pairing correlations treated by a particle-number-conserving (PNC) method. This is the first time that PNC-CSM calculat...

One of the important reactions for nucleosynthesis in the carbon burning phase in high-mass stars is the 12C+12C fusion reaction. In this study, we investigate the influences of the nuclear potentials and screening effect on astrophysically interesti...
