Published in 2019 at "Journal of High Energy Physics"

DOI: 10.1007/jhep11(2019)074

Abstract: We present a generalisation of the flavour-ordering method applied to the chiral nonlinear sigma model with any number of flavours. We use an extended Lagrangian with terms containing any number of derivatives, organised in a… read more here.
