Research summary
AI-generatedW. W. Jacobs works in experimental particle physics, studying the properties and decays of subatomic particles produced in high-energy collisions. Much of the recent work involves large international collaborations such as the Belle and Belle II experiments (which collide electrons and positrons) and the STAR experiment (which collides heavy atomic nuclei), searching for rare or forbidden particle decays and precisely measuring how particles transform. This includes hunts for phenomena that could point to physics beyond the current Standard Model, such as lepton-flavor-violating decays and possible 'dark' particles.

Publication activity has grown over the decade, with a notable spike in 2023, and averages about 17 papers per year over the last five years, consistent with membership in large experimental collaborations.
