دانلود مقاله : Dynamical model for longitudinal wave functions in light-front holographic QCD 2013

چکیده : 

Weconstruct a Schrödinger-like equation for the longitudinal wave

function of a meson in the valence q¯q sector, based on the ’t Hooft

model for large-N two-dimensional QCD, and combine this with

the usual transverse equation from light-front holographic QCD,

to obtain a model for mesons with massive quarks. The computed

wave functions are compared with the wave function ansatz of

Brodsky and de Téramond and used to compute decay constants

and parton distribution functions. The basis functions used to

solve the longitudinal equation may be useful for more general

calculations of meson states in QCD.
