LPC EFT Workshop at JHU

1 Jun 2026, 08:00 → 2 Jun 2026, 17:30 US/Eastern

462 (Bloomberg Center for Physics and Astronomy)

Andrei Gritsan (Johns Hopkins University (US)), Nick Smith (Fermi National Accelerator Lab. (US))

The 2026 LPC EFT workshop was held June 1-2, 2026, hosted by the Center Of Fundamental Interactions (COFI) at Johns Hopkins University. This workshop, now in its fourth year, focuses primarily on indirect searches for new physics at the LHC through Effective Field Theory (EFT) frameworks. Topics include: recent LHC results, beyond‑LHC connections, Standard Model EFT phenomenology, and innovative analysis ideas. Beyond‑LHC connections include EFT interpretations of precision low‑energy experiments, neutrino and flavor physics, atomic and nuclear probes, and astrophysical/cosmological constraints.

The two-day workshop was offered in a hybrid mode. Registration was open through May 15th, and the discounted hotel room block was released after May 1, 2026. Abstracts were accepted at this link through April 15th. A separate tutorial day geared towards CMS experiment students was offered; we asked that tutorial attendees be present in person.
