Abstract (data abstract)
FERMILAB-TEVATRON Collider. D0 Collaboration. First measurement of the ele ctron angular distribution parameter alpha_2 in W -& gt; e nu events as a function of W boson transverse momentum.

    Angular distributions of the emitted charged lepton is fitted to the formula d(sig)/d(pt**2)/dy/d(cos(theta*)) = const*(1 +- alpha_1*cos(theta*) + alpha_2*(cos(theta*))**2). The...
