چکیده
The current theoretical development identified as the gravitational decoupling via Complete Geometric Deformation (CGD) method that has been introduced to explore nonmetricity $Q$ effects in relativistic astrophysics. In present work, we have investigated gravitationally decoupled anisotropic solutions for strange star framework of $f(Q)$ gravity by utilizing CGD technique. To do this, started with Tolman metric ansatz along MIT Bag model equation state related hadronic matter. governing equations motions are obtained using two approaches, namely mimicking $\theta$ sector seed radial pressure and energy density fluid model. models describe self-gravitating static, compact objects whose exterior solution can be given vacuum Schwarzschild Anti-de Sitter spacetime. particular, modeled five stellar candidates, viz., LMC X-4, PSR J1614-2230, J0740+6620, GW190814, GW 170817 observational data. rigorous viability tests performed through regularity stability conditions. We observed parameter constant show a significant effect on stabilizing ensure physically realizable models. innovative feature this work is stable masses beyond $2 M_{\odot}$ without engaging exotic Therefore, study shows new perception physical significance about exploration ultra-compact astrophysical objects.

Quantum Gravity and Maximum Attainable Velocities in the Standard Model
A main difficulty in the quantization of the gravitational field is the lack of experiments that discriminate among the theories proposed to quantize gravity. Recently we showed that the Standard Model(SM) itself contains tiny Lorentz invariance violation(LIV) terms coming from QG. All terms depend on one arbitrary parameter α that set the scale of QG effects. In this talk we review the LIV for...
متن کاملThe Vainshtein mechanism in the Decoupling Limit of massive gravity
We investigate static spherically symmetric solutions of nonlinear massive gravities. We first identify, in an ansatz appropriate to the study of those solutions, the analog of the decoupling limit (DL) that has been used in the Goldstone picture description. We show that the system of equations left over in the DL has regular solutions featuring a Vainshtein-like recovery of solutions of Gener...
متن کاملHigh Mass Star Formation by Gravitational Collapse of Massive Cores
The current generation of millimeter interferometers have revealed a population of compact (r ∼< 0.1 pc), massive (M ∼ 100 M⊙) gas cores that are the likely progenitors of massive stars. I review models for the evolution of these objects from the observed massive core phase through collapse and into massive star formation, with particular attention to the least wellunderstood aspects of the pro...

متن کاملThe Indirect Limit on the Standard Model Higgs Boson Mass
Standard Model fits are performed on the most recent leptonic and b quark Z decay data from LEP and SLD, and FERMILAB data on top quark production, to obtain m t and m H. Poor fits are obtained, with confidence levels ≃ 2%. Removing the b quark data improves markedly the quality of the fits and reduces the 95% CL upper limit on m H from 169 GeV to 110 GeV.
