NA62 experiment at CERN

The main goal of the NA62 experiment at CERN, which has been collecting data since 2016, is the measurement of the ultra-rare kaon decay K⁺→π⁺νν to a 10% precision, allowing the extraction of the CKM parameter |V_td|. The experiment has a wide kaon decay and dark sector physics programme. As of 2021, I am the convener of the NA62 rare decays working group, a member of the NA62 Editorial Board, and NA62-UK spokesperson. In 2014–2019, I was the the Principal Investigator on the ERC Starting Grant 336581 "KaonLepton" dedicated to searches for lepton flavour violation in kaon decays at the NA62 experiment. I have published searches for lepton number violating kaon decays, and searches for heavy neutral lepton production in kaon decays with the NA62 Run 1 data.

NA62 (R_K phase) experiment at CERN

NA62 (R_K phase) experiment aimed at a precision test of lepton universality in kaon decays, and took data in 2007. As the physics analysis coordinator, I led a lepton universality test via a measurement of ratio BR(K^±→e^±ν)/BR(K^±→μ^±ν) decay rates.

NA48/2 experiment at CERN

NA48/2 was a high-intensity experiment devoted to studies of charged kaon decays, and took data in 2003 and 2004. I published a search for CP violating charge asymmetry (the subject of my PhD thesis, 2006) and a measurement of phase space distribution of K^±→3π^± decays, several precision measurements of rare kaon decays (K^±→π^±e⁺e⁻, K^±→π^±μ⁺μ⁻, K^±→π^±γγ), and the search for dark photon production in π⁰ decays (the most cited NA48/2 physics paper). I also acted as the run coordinator in 2003 and 2004.
