Laboratory for Particle Physics and Cosmology (LPPC)
The Laboratory for Particle Physics and Cosmology (LPPC) at Harvard University conducts cutting edge research in experimental particle physics and observational cosmology, and provides education for graduate and undergraduate students.
Research Groups
Four research groups, led by six professors, explore frontiers of fundamental physics with state-of-the-art experiments and observatories.
ATLAS Experiment
Profs. Melissa Franklin, John Huth, and Masahiro Morii lead our research with the ATLAS Experiment. Using the data from 13.6 TeV proton-proton collisions produced by the Large Hadron Collider, we measure the properties of the Higgs boson and search for new particles predicted by theories beyond the Standard Model.
IceCube Neutrino Observatory
Prof. Carlos Argüelles Delgado leads the Astroparticle Physics group, which explores properties of neutrinos using data from the IceCube Neutrino Observatory. IceCube data provides a unique window on the highest-energy neutrinos ever observed. It is an ideal place to search for beyond-the-Standard-Model effects.
Axion Dark Matter Search
Prof. Stefan Knirck's group focuses on searches for axions, hypothetical particles that could constitute cosmic Dark Matter. Prof. Knirck is currently working on two experiments, ADMX (Axion Dark Matter Experiment) and BREAD (Broadband Reflector Experiment for Axion Detection). He joined Harvard LPPC in January 2025.
Rubin Observatory
Prof. Christopher Stubbs leads his Cosmic Frontier group, working primarily on the development of the Vera C. Rubin Observatory (formerly LSST) as a tool for studying the accelerating expansion of the Universe.
