Abstract: We compute the ghost spectral function in Yang-Mills theory by solving the corresponding DysonSchwinger equation for a given input gluon spectral function. The results encompass both scaling and decoupling solutions for the gluon propagator input.… read more here.

Abstract: We discuss behaviour of the spectral gap for quantum graphs when two metric graphs are glued together. It appears that precise answer to this question can be given using a natural generalisation of ... read more here.
