FCNC transitions of Lambda(b,c) to nucleon in SM
(IOP Publishing, 2010-11)
We provide a comprehensive study of semileptonic flavor-changing neutral current transitions for Lambda(b) -> nl(+) l(-) and Lambda(c) -> pl(+) l(-) in the context of light cone QCD sum rules. Using the most general form ...
Scalar quarkonia at finite temperature
(American Physical Society, 2010-09-28)
Masses and decay constants of the scalar quarkonia, chi(Q0)(Q = b, c) with quantum numbers I-G (J(PC)) = 0(+)(0(++)), are calculated in the framework of the QCD sum rules approach both in vacuum and finite temperature. The ...
Semileptonic Bc to P-wave charmonia (Xc0,X c1,hc) transitions within QCD sum rules
(AIP Publishing, 2010-06)
The form factors of the semileptonic Bc→S(AV) ℓν(ℓ=τ,μ,e) transitions, where S and AV denote the scalar Xc0 and axial vector (Xc1,hc) mesons, are calculated within the framework of the three-point QCD sum rules. The results ...
