#### Properties of nucleon in nuclear matter: once more

(Springer, 2014-05-27)

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 ...

#### More about the B and D mesons in nuclear matter

(Springer, 2014-08-16)

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 ...

#### In-medium properties of b and d mesons

(EDP Sciences, 2014-11-24)

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.

#### Positive and negative parity hyperons in nuclear medium

(American Physical Society, 2015-09-22)

The effects of the nuclear medium on the residue, mass, and self-energy of the positive- and negative-parity Σ, Λ, and Ξ hyperons are investigated using the QCD sum-rule method. In the calculations, the general interpolating ...

#### Semileptonic b -> (d)over-bar transition in a nuclear medium

(American Physical Society, 2015-02-24)

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 ...

#### B to D(D*)ev(e) transitions at finite temperature in QCD

(American Physical Society, 2010-05-01)

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* ...

#### Impact of finite density on spectroscopic parameters of decuplet baryons

(American Physical Society, 2016-12)

The decuplet baryons, Δ, Σ∗, Ξ∗, and Ω-, 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, the negative ...

#### Scalar and vector self-energies of heavy baryons in nuclear medium

(Elsevier, 2017-04)

The in-medium sum rules are employed to calculate the shifts in the mass and residue as well as the calar and vector self-energies of the heavy Lambda(Q), Sigma(Q) and Xi(Q) baryons, with Q being b or c quark. The maximum ...

#### Properties of Sigma(Q)*, Xi(Q)* and Omega(Q)* heavy baryons in cold nuclear matter

(Elsevier Science BV, 2018-02)

The in-medium properties of the heavy spin-3/2 Sigma(Q)*, Xi(Q)*, and Omega(Q)*, baryons with Q being b or c quark are investigated. The shifts in some spectroscopic parameters of these particles due to the saturated cold ...

#### X(3872): propagating in a dense medium

(Elsevier, 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 ...
