Semileptonic $B_{c}^{-} \to D^{* 0} ℓ ν$ transition in three--point QCD sum rules and HQET with gluon condensate corrections

N. Ghahramany, R. Khosravi, K. Azizi

Taking into account the gluon condensate contributions, the form factors of the semileptonic $B_{c}^{-} \to D^{* 0} ℓ ν$ transition with $l = τ, e$ are calculated in the framework of the…

Semileptonic $D_{q} \to K_{1} ℓ ν$ and nonleptonic $D \to K_{1} π$ decays in three--point QCD sum rules and factorization approach

R. Khosravi, K. Azizi, N. Ghahramany

We analyze the semileptonic $D_{q} \to K_{1} ℓ ν$ transition with $q = u, d, s$ , in the framework of the three--point QCD sum rules and the nonleptonic $D \to K_{1} π$ decay within the Q…

Double-Lepton Polarization Asymmetries in $B_s \rar ϕ\ell^+ \ell^-$ Decay in the Fourth-Generation Standard Model

S. M. Zebarjad, F. Falahati, H. Mehranfar

In this paper, we investigate the effects of the fourth generation of quarks on the double-lepton polarization asymmetries in the $B_s \rar ϕ\ell^+ \ell^-$ decay. It is shown that…

Analysis of the $B_{q} \to D_{q} (D_{q}^{}) P$ and $B_{q} \to D_{q} (D_{q}^{}) V$ decays within the factorization approach in QCD

K. Azizi, R. Khosravi, F. Falahati

Using the factorization approach and considering the contributions of the current-current, QCD penguin and electroweak penguin operators at the leading approximation, the decay amp…

Dark Energy and Matter in 4 Dimensions From an Empty Kaluza-Klein Spacetime

M. H. Dehghani, Sh. Assyyaee

We consider the third order Lovelock equations without the cosmological constant term in an empty $n (\geq 8)$ -dimensional Kaluza-Klein spacetime $\mathcal{M}^{4}\times \mathcal{K}^…

Lowest Order Constrained Variational Calculation of Structure Properties of Protoneutron Star

G. H. Bordbar, S. M. Zebarjad, R. Zahedinia

We calculate the structure properties of protoneutron star such as equation of state, maximum mass, radius and temperature profile using the lowest order constrained variational me…
