Collision? Interaction? Event? What’s that all about?

This article gives some background on how we physicists use these three terms to talk about collider physics experiments.

Studying crowd behavior at MINERvA

These physicists lead this analysis: Minerba Betancourt (left) and Tammy Walton (middle) of Fermilab, and Anushree Ghosh (right) of Federico Santa María Technical University.

MINERvA makes the first ever measurement of the interaction planes of the three particles in a neutrino event.

Light, heavy light, and asymmetry

Liang Han (U.S.T.C., Hefei, China), Chen Wang and Yifan Xiang (undergraduates at U.S.T.C.) and Siqi Yang (U.S.T.C. and now at U. of Iowa) are the primary analysts for this measurement.

DZero has used an asymmetry in dimuon events to measure the weak-force mixing angle sin2θW.

Why study the cosmos?

The “Cosmic Frontier”

Perhaps that is one of those “duh!” questions. After all, humans have wondered about the cosmos for all of recorded history and no doubt long before writing was invented. But there is a modern component to this query.

Quarks and gluons and partons, oh my …

The proton consists of a complex mixture of quarks and gluons. Physicists use the word parton to describe all constituents of a proton.

Quarks and gluons are more generically called “partons.”
