Heavy Quark Limit

As heavy baryon ΛQ (Q=b or c) consists of a heavy quark and a scalar light diquark, we establish the Bethe-Salpeter (B-S) equation for ΛQ in the heavy quark limit. With the reasonable kernel we solve the B-S equation numerically and calculate the Isgur-Wise function as Λb→Λc.

Confinement Model

We present a quark confinement model (QCM) for the description of the low energy physics of light hadrons (meson and baryons). The model is based on two hypotheses. First, the quark confinement is realized as averaging over some vacuum gluon fields which are believed to provide the confinement of any color objects. Second, hadrons are treated as collective colorless excitations of quark-gluon interactions. The description of strong, electromagnetic and weak interactions of mesons and baryons at the low energy is given from a unique point of view.

Heavy Quark Limit

The present study investigates the decay of B to heavy meson using the soft collinear effective theory. By assigning different loop momenta, the factorization has been tested and it is found to be valid to all orders in the perturbation theory. It is noted that theory contains one hard collinear and two soft modes depending upon virtuality of different momenta. In the next step, symmetry-conserving relations (in heavy quark limits) to the form factors have been studied. These relations are then used to parametrize the form factors to get symmetry-breaking corrections. These symmetry-breaking corrections can be calculated using perturbative (vertex corrections) as well as nonperturbative (hard spectator interactions) QCD. It is found that in the heavy quark limit, these symmetry contributions do not contribute to the form factors that appear in physical observables for the case of [Formula: see text] decays which are contrary to the heavy-to-light meson decays.
