We develop an inverse matrix method to solve for resonance masses from a dispersion relation obeyed by correlation function. Given the operator product expansion (OPE) of function in deep Euclidean region, we obtain nonperturbative spectral density, which exhibits structures naturally. The value gluon condensate OPE is fixed producing $\rho$ meson mass formalism, and then input into relations s...

In a sector characterised by patenting, direct appropriations and returns from investment, the Structural Genomics Consortium (SGC) constitutes radically different public-private entirely ope...

We derive the dependence of leading-twist pion light-cone distribution amplitude (LCDA) on a parton momentum fraction $x$ by directly solving dispersion relations for moments with inputs from operator product expansion (OPE) corresponding correlation function. It is noticed that these must be organized into those Gegenbauer coefficients first in order to avoid ill-posed problem appearing conver...
