Future {nu}{sub {mu}}N deep-inelastic scattering measurements of sin{sup 2}{theta}{sub W} and {rho}
- Fermi National Accelerator Lab., Batavia, IL (United States)
This paper presents the current status of results on R{sub {nu}} and R{sub {anti {nu}}} and discusses planned measurements which will significantly reduce old errors; the next generation of neutrino-nucleon deep-inelastic measurements of sin{sup 2}{theta}{sub W} and {rho} will test the radiative corrections to the Standard Model as strongly as will the determinations of M{sub W}, M{sub Z}, and A{sub LR} at hadronic and e{sup +}e{sup {minus}} colliders. It is important to realize that the information from {nu}{sub {mu}}N scattering is not redundant given the collider determinations. DIS determinations have a unique role in probing for physics beyond the Standard Model. The quantities usually measured in deep-inelastic {nu}N scattering are the Llewellyn Smith (LS) variables R{sub {nu}} = {sigma}{sub {nu}}{sup NC}/{sigma}{sub {nu}}{sup CC} and R{sub {anti {nu}}}, the corresponding quantity for antineutrinos; the results are generally quoted in the Sirlin scheme. R{sub {nu}} depends on sin{sup 2}{theta}{sub W} much more strongly than it does on {rho}; the reverse is true for R{sub {anti {nu}}}. Hence in order to measure sin{sup 2}{theta}{sub W} and {rho} independently both measurements must be made.
