A collinear shower algorithm for NSL non-singlet fragmentation

Abstract We formulate a collinear partonic shower algorithm that achieves next-to-single-logarithmic (NSL, α s n L n − 1 $$ {\alpha}_s^n{L}^{n-1} $$ ) accuracy for collinear-sensitive non-singlet fragmentation observables. This entails the development of an algorithm for nesting triple-collinear spl...
