We calculate the polarization of prompt J/ψ and Υ(1S) production using the color evaporation model at leading order. We present the polarization parameter x _F as a function of center of mass energy and rapidity in p+p collisions. We also compare the x _F dependence to experimental results in p+Cu and π+W collisions, and predict the x _F dependence in p+Pb collisions at fixed-target energies.

Journal Article Ablikim, M. ; Achasov, M. N. ; Ahmed, S. ; ... December 2017 - Physical Review D

Using the data samples of (1310.6 ± 7.2) × 10 ⁶ J / ψ events and (448.1 ± 2.9) × 106 (3686) events collected with the BESIII detector, we search for the rare decays J / ψ → D ⁰e ⁺e ^- + c.c. and (3686) → D ⁰e ⁺e ^- + c.c.. No significant signals are observed and the corresponding upper limits on the branching fractions at the 90% confidence level are determined to be B( J /more » ψ → D0e+e- + c.c.) < 8.5 × 10 ^-8 and B( (3686) → D0e+e- + c.c.) < 1.4 × 10 ^-7, respectively. Our limit on B( J / ψ → D ⁰e ⁺e ^- + c.c.) is more stringent by two orders of magnitude than the previous results, and the B( (3686) → D ⁰e ⁺e ^- + c.c.) is measured for the first time. « less

Measurement of the $Λ_{b}$ polarization and angular parameters in $Λ_{b} \to J / ψ Λ$ decays from $p p$ collisions at $\sqrt{s} = 7$ and 8 TeV

Journal Article Sirunyan, A. M. ; Tumasyan, A. ; Adam, W. ; ... April 2018 - Physical Review D

An analysis of the bottom baryon decay Λ _b → J/ψ(→μ ⁺μ ^-)Λ(→ pπ ^-) is performed to measure the Λb polarization and three angular parameters in data from pp collisions at √s = 7 and 8 TeV, collected by the CMS experiment at the Large Hadron Collider. The Λ _b polarization is measured to be 0.00 ± 0.06(stat) ± 0.06(syst) and the parity-violating asymmetry parameter is determined to be 0.14 ± 0.14(stat) ± 0.10(syst). Furthermore, the measurements are compared to various theoretical predictions, including those from perturbative quantum chromodynamics.
