Neutral current cross-sections for neutrinos on protons

Abstract

Defining the ratios rp =σ(vp →vx)/σ(vp →μ- x) and {Mathematical expression} we obtain the bounds 0.28 ≤rp ≤ 0.61 and {Mathematical expression} using only the parton model and the data of CDHS group with iron target. We also give the complete set of parton-model relations which would allow the determination of all the neutral-current coupling constants from inclusive cross sections alone. © 1978 Indian Academy of Sciences.
