Unveiling the polarisation of weak bosons at the LHC: Monte Carlo automation and neural-network strategies
Accessing the polarisation state of weak represents a crucial step to improve our understanding of the electroweak-symmetry-breaking mechanism that is realised in nature. The recent ATLAS and CMS results have started triggering multiple efforts in the theory community, comprising the precise and accurate calculation of polarised-boson signals, as well as a number of novel approaches that enhance the sensitivity to polarisation. I will focus the talk on two main topics: the recently achieved NLOPS matching for polarised-boson pair production, and a neural-network strategy for the tagging of longitudinally polarised bosons at the LHC.
