The primary goal of this 3‐day workshop is to educate the LHC community about the scientific utility of likelihoods. We shall do so by describing and discussing several real‐world examples of the use of likelihoods, including a one‐day in‐depth examination of likelihoods in the Higgs boson studies by ATLAS and CMS.
The workshop will start with two pedagogical lectures that introduce likelihood concepts and terminology. These lectures are followed, in the afternoon of Day 1, by a moderated discussion that focuses on the concepts and issues raised in the lectures. Day 1 ends with several presentations that illustrate the use of likelihoods in Higgs and Beyond the Standard Model (BSM) research. The goal here is to get feedback from researchers who have used Higgs and BSM results in their work.
Given the importance of the work on the Higgs boson, we shall devote the second day of the workshop to the thorough deconstruction of likelihood usage in the Higgs boson work by ATLAS and CMS. The goal is to shed a bright light on the many details, and assumptions, that underlie the likelihoods used in the recently published results.
The final day of the workshop covers the use of likelihoods in BSM work and ends with an examination and discussion of the concrete steps needed to make the publication of likelihoods by the LHC community systematic and routine.
