Searching for physics beyond the Standard Model (BSM) is a major part of the research programme at the LHC experiments. Nearly all of these searches pick a signal model that addresses one or more of the experimental (e.g., dark matter) or…

December 2020 - February 2021
The idea of the Curious Cryogenic Fish dates back to 2017. While observing the complex detectors and instrumentation being assembled for the ProtoDUNE experiments at the CERN Neutrino Platform, I started thinking that it would have been great to…

The ALICE time projection chamber (TPC) is a big, gas-filled cylinder (with a hole in the centre to accommodate the silicon tracker), where the charge produced by ionising radiation is projected onto detectors arranged in the two endplates.…

Antiprotons as a probe to study short-lived isotopes remain unexploited despite past pioneering works with stable nuclei. In particular, low-energy antiprotons offer a unique prospect in terms of sensitivity to the neutron and proton densities at…

Ernest Rutherford, in 1899, separated radioactive emissions into two types: alpha and beta. Becquerel, in 1900, measured the mass-to-charge ratio of beta particles and identified them as electrons. The theory of β decay was developed by Fermi in…

The Monte Carlo method is used primarily for calculations that are too difficult or even impossible to perform analytically, so that as our experiments and theories become more accurate, we become more dependent on the quality of our MC calculations…

In statistical data analysis, “likelihood” is a key concept that is closely related to, but crucially distinct from, the concept of “probability”, which is often a synonym in everyday English. In this article, I first lay some necessary foundations…
