B to D(D*)ev(e) transitions at finite temperature in QCD
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* ... 
Effects of a dense medium on parameters of doubly heavy baryons
The spectroscopic properties of the doubly heavy spin1/2 baryons Xi(QQ'), Xi(QQ')', Omega(QQ'), and Omega(QQ')', with heavy quarks Q and Q' being b or/and c, are investigated in cold nuclear matter. In particular, the ... 
Fate of the doubly heavy spin3/2 baryons in a dense medium
We investigate the behavior of the doubly heavy spin3/2 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 ... 
Inmedium Properties of B and D Mesons
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. 
Modifications on parameters of Z(4430) in a dense medium
The charmoniumlike resonance Z(c)(3900) and its excited state Z(4430) are among the particles that are serious candidates for double heavy tetraquarks. Calculations of different parameters associated with these states ... 
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 BN and DN scattering lengths and an extra ... 
The newly observed Zcs<mml:msup>(3985)</mml:msup> state: in vacuum and a dense medium
We report on some properties of the newly observed charged hiddencharmed open strange Zcs(3985) state by BESIII Collaboration. Assigning the quantum numbers JP=1+ and the quark composition cc<overbar></mml:mover>su<ove ... 
Positive and negative parity hyperons in nuclear medium
The effects of the nuclear medium on the residue, mass, and selfenergy of the positiveand negativeparity Sigma, Lambda, and Xi hyperons are investigated using the QCD sumrule method. In the calculations, the general ... 
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 ... 
Properties of Z(c)(3900) tetraquark in a cold nuclear matter
The study of medium effects on properties of particles embedded in nuclear matter is of great importance for understanding the nature and internal quarkgluon organization as well as exact determination of the quantum ... 
Scalar and vector selfenergies of heavy baryons in nuclear medium
The inmedium sum rules are employed to calculate the shifts in the mass and residue as well as the scalar and vector selfenergies of the heavy Lambda(Q), Sigma(Q) and Xi(Q) baryons, with Q being b or c quark. The maximum ...

X (3872): propagating in a dense medium
In cold nuclear matter, the shifts in the mass and currentmeson coupling as well the vector self energy of the exotic X(3872) are calculated using the diquarkantidiquark current within the framework of the inmedium ...
