Angular decay coefficients of J/ψ mesons at forward rapidity from p+p collisions at root s=510 GeV
Original language description
We report the first measurement of the full angular distribution for inclusive J/ψ->μ+μ- decays in p + p collisions at root s =510 GeV. The measurements are made for J/ψ transverse momentum 2<p_T<10 GeV/c and rapidity 1.2<y<2.2 in the Helicity, Collins-Soper, and Gottfried-Jackson reference frames. In all frames the polar coefficient λθ is strongly negative at low p_T and becomes close to zero at high p_T, while the azimuthal coefficient λϕ is close to zero at low p_T, and becomes slightly negative at higher p_T. The frame-independent coefficient λ~ is strongly negative at all p_T n all frames. The data are compared to the theoretical predictions provided by nonrelativistic quantum chromodynamics models.
