Prompt J/ψ Polarization at the Tevatron
نویسنده
چکیده
The polarization of prompt J/ψ at the Tevatron is calculated within the nonrelativistic QCD (NRQCD) factorization framework. The contribution from radiative decays of P-wave charmonium states decreases, but does not eliminate, the transverse polarization at large transverse momentum. The prediction agrees with measurements from the CDF collaboration at intermediate values of pT , but disagrees at the large values of pT measured.

Polarized J / ψ from χ cJ and ψ ′ Decays at the Tevatron
We calculate the partonic cross sections for the hadroproduction of polarized χcJ mesons using the factorization formalism of nonrelativistic QCD. We also describe how the polarization is passed on to the J/ψ mesons in the radiative feed-down χcJ → J/ψ+ γ and in the double-cascade decays of ψ′ mesons via χcJ intermediate states. These represent the missing ingredients needed to predict the pola...
متن کاملUnifying aspects of polarization of vector mesons from hard production in DIS and at Tevatron
Virtual photons have both the transverse and longitudinal polarization. In the inclusive DIS the impact of longitudinal photons, quantified by R = σL/σT ∼ 0.2, is marginal, but in diffractive DIS with excitation of small mass hadronic states or exclusive diffraction into vector mesons, QCD predicts R 1 in agreement with the experiment. After a brief review of the modern status of QCD theory of ...
متن کاملCurrent Issues in Quarkonium Production
As a stringent test of the nonrelativistic QCD factorization approach for inclusive heavy-quarkonium production in high-energy hadron collision, the polarized heavyquarkonium production at the Tevatron is discussed. The polarization of prompt J/ψ at the Tevatron is predicted within the nonrelativistic QCD factorization framework. The contribution from radiative decays of P-wave charmonium state...
متن کاملSpin-Flip Interactions and the Puzzle of ψ′s Polarization at Tevatron
Nonrelativistic QCD provides a systematic approach for inclusive decays and productions of a quarkonium. By taking color-octet components into account, the approach can explain the ψ-anomaly at Tevatron, where the measured production rate at large transverse momentum p⊥ is in order of magnitude larger than the predicted with color-singlet components only. With the approach one can predict that ...
متن کاملDouble gluon fragmentation to J / ψ pairs at the Tevatron
It has been proposed that the large cross sections for prompt ψ, ψ ′ , and χ c production at the Fermilab Tevatron p¯ p collider can be explained by a dominant color-octet term in the fragmentation function for a gluon to split into quarkonium. We show that this mechanism makes testable predictions for double-quarkonium ψψ, ψψ ′ , ψχ c , ψΥ and ψχ b production, as well as for W ψ production, us...
