Nucleon tensor form factors induced by isovector and isoscalar currents in QCD
The main problem of QCD is to understand the structure of hadrons and their properties in terms of quarks and gluons. Nucleon charges defined as matrix elements of vector, axial, and tensor currents between nucleon states contain complete information about the quark structure of the nucleon. These charges are connected with the leading twist unpolarized qðxÞ, the helicity qðxÞ, and transversity...
متن کاملNucleon form factors induced by isovector and isoscalar axial–vector currents in QCD
Using the most general form of the baryon current, nucleon form factors, induced by isovector and isoscalar axial–vector currents, are studied in the framework of light cone QCD sum rule approach. Comparison of our results on form factors with the existing results and lattice calculations are presented.

متن کاملPrecision spectroscopy in light isovector , isoscalar and hybrid mesons
We discuss all-to-all propagators in the context of high statistical precision determinations of the isovector and isoscalar meson spectrum. In particular we look at the method of Ref. [2] that incorporates the low-lying eigenmodes and variance-reduced stochastic estimation. We find significant low-lying eigenmode dependence of mass determinations, with the number of required modes varying with...
متن کاملImproved approach to the heavy - to - light form factors in the light - cone QCD sum rules ∗
A systematic analysis shows that the main uncertainties in the form factors are due to the twist-3 wave functions of the light mesons in the light-cone QCD sum rules. We propose an improved approach, in which the twist-3 wave functions doesn’t make any contribution and therefore the possible pollution by them can be avoided, to re-examine B → π semileptonic form factors. Also, a comparison betw...
متن کاملFe b 20 03 Penguin induced B → η transition form factor in light cone QCD
We calculate the penguin form factor for the B → ηl+l− decay. This form factor is calculated in light cone QCD sum rules, including contributions from wave functions up to twist–4, as well as mass corrections of the light η meson.
