“…The mass spectra of singly charmed baryons [2,52,53,54] are generated by the Hamiltonian in the hypercentral Constitute Quark Model (hCQM). Here, m = mρm λ mρ+m λ is the reduced mass and x is the six dimensional radial hypercentral coordinate of the three body system.…”

The magnetic moments, transition magnetic moments and the radiative decay widths of singly charmed baryons are calculated with J P = 1 2 + and J P = 3 2 + in the constitute quark model. Further, the strong decay rates for S, P and D wave transitions are also presented. The singly charmed baryon masses used in the calculations were obtained from the hypercentral Constitute Quark Model (hCQM) without and with first order relativistic correction. Obtained results are compared with experimental observation as well as with the other theoretical predictions.

The idea of this article is to examine the effects on dynamics of dissipative gravitational collapse in nonstatic cylindrical symmetric geometry by using Misner-Sharp concept in framework of metric f(R) gravity theory. In this interest, we extended our study to the dissipative dark source case in both forms of heat flow and the free radiation streaming. Moreover, the role of different quantities such as heat flux, bulk, and shear viscosity in the dynamical equation is evaluated in thorough version. The dynamical equation is then coupled with full causal transportation equations in the context of Israel-Stewart formalism. The present scheme explains the physical consequences of the gravitational collapse and that is given in the decreasing form of inertial mass density which depends on thermodynamics viscous/heat coupling factors in background of f(R) theory of gravity. It is very interesting to tell us that the motives of this theory are reproduced for f(R)=R into general theory of relativity that has been done earlier.

“…[46] Various outcomes of charged cylindrical collapse models inspired by different matter properties are presented. [47][48][49] Despite the aforementioned GR consequences, several novel findings have reported in consideration of models of gravitationally collapsing stars in the f (R) context. Various theorists [4,6,7,50,51] have contributed adequate insights covering this phenomenon within the generalized versions of f (R) gravity.…”

The current paper studied the dynamics of shear‐free and spherically symmetric collapsing stars by incorporating the features of anisotropic dissipative fluid in the realm of gravity. A complete radiative star model that describes the early static configuration obeying the embedding class 1 approach is generated. To acquittance the exact solutions of the geometric variables, a specific form of pressure anisotropy along with a time‐dependent Karmarkar condition is employed, leading to a spacetime solution that seems to be potentially reliable and regular throughout the collapse process. The matching conditions have been thoroughly investigated between the interior geometry and the Vaidya outgoing solution over the junction interface. The physical attributes of our solutions to the Einstein field equations under two viable and cosmologically well‐consistent models of are manifested. The presented features are in a stable equilibrium state and sustainable to model a dynamic structure of gravitational collapse without forming the black hole.
