The Strange-Antistrange Asymmetry, The NuTeV Measurement and a Peek at Future Prospects.
- Fermilab (United States)
The strange asymmetry measurement from NuTeV is discussed, followed by a brief look at measurement prospects from other current and future neutrino DIS experiments. The NuTeV measurement of the difference between the strange and antistrange quark distributions from dimuon events utilizes the first complete NLO QCD description of the process. Dimuon events, resulting from the semi-muonic decay of charmed particles produced in charged current neutrino interactions, allow direct study of the strange quark content of the nucleon. NuTeV's sign selected beam produced uniquely pure samples of neutrino and antineutrino initiated dimuon events, allowing independent measurement of the strange and antistrange quark distributions.
