Project Details


“Colegio de Física Fundamental e Interdisciplinaria de las Américas (COFI)” in Old San Juan, Puerto Rico will hold a workshop to discuss the challenges on precision electroweak (EW) physics at the Large Hadron Collider (LHC) with the current 13 TeV data sample and as part of the preparations for future data at higher instantaneous luminosity.

The past decade has witnessed tremendous progress in understanding electroweak physics. The standard model (SM) of particle physics can be challenged using precise measurements of electroweak probes based on the large LHC data samples. This requires a higher level of accuracy and confidence on the inputs used in the analyses and in the interpretation of the results in addition to more advanced analysis techniques.

Current concerns include uncertainties on the theoretical corrections (both electroweak and QCD) and the inputs needed to described proton-proton collisions (parton distribution functions, as, etc.), and subtleties in combining/fitting the electroweak data. These issues must be understood for many of the crucial measurements, like: (i) the W and Higgs bosons and top quark masses, (ii) the weak mixing angle, (iii) diboson scattering, and (iv) rare and/or forbidden decays of bosons.

The purpose of the workshop is to bring together both theorists and experimentalists in these different areas to improve our understanding and perform the best possible precision electroweak measurements. An important focus will be on the interplay between the various theoretical inputs needed to find deviations, if any, to the expected electroweak observables and the opportunities to exploit measurements to calibrate theoretical predictions. We plan to develop a strategic plan for theory and LHC program through a set of detailed talks and discussions.
