Divergences in anomalous dimension matrices of quarks at three loops: Explanation and simple solution
Adrian Lewandowski
Three-loop counterterms for the Standard Model (SM) revealed that the matrix of anomalous dimensions () of quarks is divergent in the limit unless a carefully chosen n…

Vector-scalar mixing to all orders, for an arbitrary gauge model in the generic linear gauge
Adrian Lewandowski
I give explicit fromulae for full propagators of vector and scalar fields in a generic spin-1 gauge model quantized in an arbitrary linear covariant gauge. The propagators, express…

LSZ-reduction, resonances and non-diagonal propagators: gauge fields
Adrian Lewandowski
We analyze in the Landau gauge mixing of bosonic fields in gauge theories with exact and spontaneously broken symmetries, extending to this case the Lehmann-Symanzik-Zimmermann (LS…
