1 Nonperturbative corrections to the quark self - energy
نویسنده
چکیده
Nonperturbative self-energy of a bound quark is computed gauge-invariantly in the framework of background perturbation theory. The resulting ∆m 2 q is negative and is a universal function of string tension and current quark mass. The shift of hadron mass squared, M 2 , due to ∆m 2 q is negative, large for light quarks, and solves the long-standing problem of Regge intercepts in relativistic quark models.

The leading nonperturbative QCD corrections to the one gluon exchange quark-quark, quark-antiquark and q ¯ q pair-excitation potentials are derived by using a covariant form of nonlocal two-quark and two-gluon vacuum expectation values. Our numerical calculation indicates that the correction of quark and gluon condensates to the quark-antiquark potential improves the heavy quarkonium spectra to...

We discuss nonperturbative contributions to the inclusive rareB decays B → Xsγ and B → Xs`+`−. We employ an operator product expansion and the heavy quark effective theory to compute the leading corrections to the decay rate found in the free quark decay model, which is exact in the limit mb →∞. These corrections are of relative order 1/mb , and may be parameterised in terms of two low-energy p...
متن کاملInclusive semileptonic B decays
In the framework of the Standard Model, the quark sector is characterised by a rich pattern of flavourchanging transitions, described by the CabibboKobayashi-Maskawa (CKM) matrix. The quark transitions B → Xclν and B → Xulν provide a way for determining these CKM matrix elements. This report reviews the experimental measurements used to extract the quark mixing parameters |Vcb| and |Vub| from t...
متن کاملOn the short distance nonperturbative corrections in heavy quark expansion
We study the corrections due to renormalons to the heavy hadron decay width. The renormalons contribution estimated in terms of finite gluon mass based on the assumption that the gluon mass represents the short distance nonperturbative effects in the standard OPE (and hence in the heavy quark expansion). We found that the corrections are about 10% of the leading decay rate. We point out the imp...
