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 ...
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 ...
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 ...
