Enhanced production of hadrons with $s$-quark content has been observed in $pp$ collisions at LHC, and earlier in collisions of heavy nuclei. We review the string hadronisation formalism and correc- tions from rope hadronisation and colour…

A new release of the Monte Carlo event generator Herwig (version 7.3) has been launched. This iteration encompasses several enhancements over its predecessor, version 7.2. Noteworthy upgrades include: the implementation of a…

We show that the production rates of light-flavoured mesons and baryons in inelastic pp and p$\bar{p}$ collisions can be described by a simple approach used to describe data obtained in $e^{+}e^{-}$ annihilation. Based on the idea of string…
