The effect of z^prime boson on same-sign dimuon charge asymmetry in $ b_q^0 - bar b_q^0$ system
The recent observation of the same-sign dimuon charge asymmetry in the B system by the D0 collaboration has 3.9 sigma deviation from the standard model prediction. However, the recent LHCb data on
Effect of both Z and Z^prime - mediated flavor-changing neutral currents on $B_s$ decays into $tau^+tau^-$
In recent years, $B_s$ decays into $tau^+tau^-$ has attracted a lot of attention since it is very sensitive to the structure of standard model (SM) and potential source of new physics beyond SM. In
Study of Bs0 → µ+µ− and Bd0 → µ+µ− decays in flavor-changing Z′ models
Recently, the first evidence for the decay Bs0 → μ+μ− has been announced by the LHCb Collaboration and the measured branching ratio B(s0 → μ+) = (3.2−1.2+1.5) × 10−9 is in good agreement with the

When gravitational wave is absorbed by a black hole, for the energy of gravitational wave greater than the critical energy of the black hole, there is flow of quantum vacuums away from the black
Quantum Black Hole and the Origin of the Universe
Classically a black hole absorbs everything that comes too close and does not emit anything. However, when quantum effects are considered black holes create and emit particles. If the whole mass of
Planck Scale Particles in the Universe
Planck’s units when multiplied by the magic number ( 61 10 ) give the well-known physical properties of the universe, mass, length and time. Planck’s units divided by magic number gives the mass,
Study of Bs0 → ℓ+ℓ−γ decays in a nonuniversal Z′ model
We investigate [Formula: see text] decays in a nonuniversal [Formula: see text] model derived from the extension of the Standard Model (SM). Considering the [Formula: see text]-mediated

The effect of magnetic fields on the leptonic decay of charged B meson B− → l-v- is investigated. The decay rate of the process is calculated both in the absence and presence of magnetic field. The
Black Mass in the Universe
There is creation of mass due to strong interaction among the three quarks inside the nucleons. The sum of the masses of these quarks is approximately 1% of the mass of the nucleons. Analogous to
