چکیده
Stimulated by the $P_{cs}(4459)$ reported LHCb Collaboration, we perform a single $\Xi_c\bar{D}^*$ channel and coupled $\Xi_c\bar{D}^*/\Xi_c^*\bar{D}/\Xi_c^{\prime}\bar{D}^*/\Xi_c^*\bar{D}^*$ analysis using one-boson-exchange model. Our results indicate that newly cannot be pure molecular state, but bound state with $I(J^P)=0(3/2^-)$, where $\Xi_c^*\bar{D}$ components are dominant. Meanwhile, find interactions from $\Xi_c^{\prime}\bar{D}^*$ system $0(1/2^-)$, $\Xi_c^{*}\bar{D}$ $1(3/2^-)$, $\Xi_c^{*}\bar{D}^*$ $1(1/2^-)$ strongly attractive, one can expect possible strange hidden-charm or resonant structures near these thresholds assigned quantum numbers.

How large can the crust of a strange star be?
The effect of the magnetic field on the electrostatic potential of electrons inside and in close vicinity outside the quark surface of the star is studied. Depending on the value of the crust potential and the electron chemical potential at the base of the nuclear crust, we find that the strong surface magnetic field, 1.0 × 1014 ≤ H ≤ 3.0 × 1016 Gauss leads to a considerable reduction of the el...
متن کاملPredictions of charged charmoniumlike structures with hidden-charm and open-strange channels.
We propose the initial single chiral particle emission mechanism, with which the hidden-charm dikaon decays of higher charmonia and charmoniumlike states are studied. Calculating the distributions of differential decay width, we obtain the line shape of the J/ψK(+) invariant mass spectrum of ψ(i)→J/ψK(+)K(-), where ψ(i)=ψ(4415), Y(4660), and ψ(4790). Our numerical results show that there exist ...
متن کاملCharm and hidden charm scalar mesons in the nuclear medium
We study the renormalization of the properties of the low lying charm and hidden charm scalar mesons in a nuclear medium, concretely of the D s0 (2317), D 0 (2400) and the theoretical hidden charm state X(3700). We find that for the D s0 (2317), with negligible width at zero density, the width becomes about 100 MeV at normal nuclear matter density, while in the case of the X(3700) the width bec...
متن کاملStrange stars : how dense can their crust be ? ?
The strong electric field at the surface of a strange star is discussed, and a self-consistent model is proposed to calculate its capability of supporting a “normal” nuclear material crust.We find that the electric field is already not able to support the crust even when the bottom density of the crust is still considerably lower than the neutron drip point, which means that it is not the neutr...
متن کاملCan Doubly Strange Dibaryon Resonances be Discovered at RHIC?
The baryon-baryon continuum invariant mass spectrum generated from ultrarelativistic nucleus + nucleus collision data may reveal the existence of doubly-strange dibaryons not stable against strong decay if they lie within a few MeV of threshold. Furthermore, since the dominant component of these states is a superposition of two color-octet clusters which can be produced intermediately in a colo...
