B to D(D*)ev(e) transitions at finite temperature in QCD
(Amer Physical Soc, 2010)
In this article, we work out the properties of the B, D, and D* mesons as well as the B -> D(D*)ev(e) decay properties at finite temperature QCD. The behavior of the masses, decay constants and widths of the B, D, and D* ...
Properties of nucleon in nuclear matter: once more
We calculate the mass and residue of the nucleon in nuclear matter in the frame work of QCD sum rules using the nucleon's interpolating current with an arbitrary mixing parameter. We evaluate the effects of the nuclear ...
Semileptonic B -> (D)over-bar transition in a nuclear medium
(Amer Physical Soc, 2015)
We study the semileptonic tree-level B -> (D) over bar transition in the framework of QCD sum rules in a nuclear medium. In particular, we calculate the in-medium form factors entering the transition matrix elements defining ...
In-medium Properties of B and D Mesons
(E D P Sciences, 2014)
The shifts in the masses and decay constants of B and D mesons in nuclear medium are calculated in the frame work of QCD sum rules. The results obtained are compared with the existing theoretical predictions.
More about the B and D mesons in nuclear matter
We calculate the shifts in decay constants of the pseudoscalar B and D mesons in nuclear medium in the frame work of QCD sum rules. We write those shifts in terms of the B-N and D-N scattering lengths and an extra ...
Positive and negative parity hyperons in nuclear medium
(Amer Physical Soc, 2015)
The effects of the nuclear medium on the residue, mass, and self-energy of the positive-and negative-parity Sigma, Lambda, and Xi hyperons are investigated using the QCD sum-rule method. In the calculations, the general ...
Impact of finite density on spectroscopic parameters of decuplet baryons
(Amer Physical Soc, 2016)
The decuplet baryons, Delta. Sigma*, Xi*, and Omega(-), are studied in nuclear matter by using the in-medium QCD sum rules. By fixing the three-momentum of the particles under consideration at the rest frame of the medium, ...
Fate of the doubly heavy spin-3/2 baryons in a dense medium
(Amer Physical Soc, 2019)
We investigate the behavior of the doubly heavy spin-3/2 baryons in cold nuclear matter. In particular, we study the variations of the spectroscopic parameters of the ground state Xi(QQ')* and Omega(QQ')* particles, with ...
Scalar and vector self-energies of heavy baryons in nuclear medium (vol 960, pg 147, 2017)

X (3872): propagating in a dense medium
(Elsevier Science Bv, 2018)
In cold nuclear matter, the shifts in the mass and current-meson coupling as well the vector self energy of the exotic X(3872) are calculated using the diquark-antidiquark current within the framework of the in-medium ...
