NONPERTURBATIVE HQET AT ORDER 1/m
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2010)
We summarize the first results for masses and decay constants of bottom-strange (pseudo-scalar and vector) mesons from nonperturbatively renormalized heavy-quark effective theory (HQET), using lattice-QCD simulations in ...
BROKEN SU(8) AND HADRONIC MASS RELATIONS IN HEAVY-QUARK EFFECTIVE THEORY
(World Scientific Publ Co Pte Ltd, 1995-07-20)
Mass relations for hadrons containing a single heavy quark (charm or beauty) are studied from the viewpoint of a quark model with broken SU(8) symmetry, developed by Hendry and Lichtenberg some time ago, in comparison to ...
D*D rho vertex from QCD sum rules
(ELSEVIER SCIENCE BV, 2011)
We calculate the form factors and the coupling constant in the D*D rho vertex in the framework of QCD sum rules. We evaluate the three-point correlation functions of the vertex considering D, rho and D* mesons off-shell. ...
Heavy quarkonium production through the top quark rare decays via the channels involving flavor changing neutral currents
(Springer, 2018-08-17)
In the paper, we discuss the possibility of observation of heavy quarkoniums via the processes involving flavor changing neutral currents (FCNC). More explicitly, we systematically calculate the production of heavy charmonium ...
HQET at order 1/m: II. Spectroscopy in the quenched approximation
(SPRINGER, 2010)
Using Heavy Quark Effective Theory with non-perturbatively determined parameters in a quenched lattice calculation, we evaluate the splittings between the ground state and the first two radially excited states of the B(s) ...
Born-Oppenheimer approximation in an effective field theory language
(2018-01-01)
The Born-Oppenheimer approximation is the standard tool for the study of molecular systems. It is founded on the observation that the energy scale of the electron dynamics in a molecule is larger than that of the nuclei. ...
QCD sum rules calculation of heavy Λ semileptonic decay
(Elsevier B.V., 1998-07-09)
We set up sum rules for heavy lambda decays in a full QCD calculation which in the heavy quark mass limit incorporates the symmetries of heavy quark effective theory. For the semileptonic Λc decay we obtain a reasonable ...

(Amer Physical Soc, 2018-01-25)
The Born-Oppenheimer approximation is the standard tool for the study of molecular systems. It is founded on the observation that the energy scale of the electron dynamics in a molecule is larger than that of the nuclei. ...
Quark-Antiquark Effective Potential in Symplectic Quantum Mechanics
(2022-01-01)
In this paper, we study within the structure of Symplectic Quantum Mechanics a bidimensional nonrelativistic strong interaction system which represent the bound state of heavy quark-antiquark, where we consider a Cornell ...
Lepton transverse polarization in the B -> Dl nu(l) decay due to the electromagnetic final state interaction
(American Physical Soc, 2002-10-01)
The effect of lepton transverse polarization in B-0-->D(-)l(+)nu(l), B+-->(D) over bar (0)l(+)nu(l) decays (l=tau,mu) is analyzed within the framework of the standard model in the leading order of heavy quark effective ...
