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.

Exclusive production: shedding light with grazing protons

CMS observes the creation of W boson from the collision of photos in the proton’s magnetic field.

Audio note: this episode contains some mysterious drop-outs of audio frames. We are investigating the cause of this–it should be solved by the next episode.

Happy hunting grounds

The data from the Tevatron is particularly sensitive to the detection of new, electrically-charged massive particle like a W-Prime.
