The forward production of a Higgs boson in proton-proton collisions can be
described within high-energy QCD factorization. The key ingredient is the so-called Higgs impact factor, whose calculation in the next-to-leading order for infinite top mass turned out to be very challenging.
We investigate the origin of next-to-leading power corrections to the event shapes thrust and $c$-parameter, at next-to-leading order.
For both event shapes we trace the origin of such terms in the exact
calculation, and compare with a recent approach involving
the eikonal approximation and momentum shifts that follow from the Low-Burnett-Kroll-Del Duca theorem. We assess the differences...
The NA62 experiment at CERN collected the world's largest dataset of charged kaon decays in 2016-2018, leading to the first measurement of the branching ratio of the ultra-rare $K^+ \rightarrow \pi^+ \nu \bar\nu$ decay, based on 20 candidates.
In this talk NA62 reports new results from the analyses of rare kaon and pion decays, using data samples collected in 2017-2018. A sample of $K^+...
