被引用回数:2 パーセンタイル:13.82(Astronomy & Astrophysics)We report the first measurement of the full angular distribution for inclusive decays in collisions at GeV. The measurements are made for transverse momentum GeV/ and rapidity in the Helicity, Collins-Soper, and Gottfried-Jackson reference frames. In all frames the polar coefficient is strongly negative at low and becomes close to zero at high , while the azimuthal coefficient is close to zero at low , and becomes slightly negative at higher . The frame-independent coefficient is strongly negative at all in all frames. The data are compared to the theoretical predictions provided by nonrelativistic quantum chromodynamics models.
