“…However, prompt production studies carried out at the Tevatron collider in the early 1990s [3] made clear that NRQCD calculations, based on the leading-order (LO) colour-singlet model (CSM), failed to describe the absolute value and the transverse momentum ( p T ) dependence of the charmonium production cross-section and polarization data. Subsequently, the inclusion of colour-octet amplitudes in the NRQCD model has reduced the discrepancy between theory and experiment, albeit at the price of tuning ad hoc some matrix elements [2].…”

The differential cross-section for the inclusive production of ψ(2S) mesons in pp collisions at has been measured with the LHCb detector. The data sample corresponds to an integrated luminosity of 36 pb−1. The ψ(2S) mesons are reconstructed in the decay channels ψ(2S)→μ+μ− and ψ(2S)→J/ψπ+π−, with the J/ψ meson decaying into two muons. Results are presented both for promptly produced ψ(2S) mesons and for those originating from b-hadron decays. In the kinematic range pT(ψ(2S))≤16 GeV/c and 2

“…The J/ ψ production cross section measurements at the Tevatron [1, 2] were found to disagree by about a factor of 50 with theoretical color-singlet calculations [3]. Soon after, the CDF experiment reported a χ c2 / χ c1 cross section ratio that extended up to p T (J/ ψ )≃10 GeV/ c , where p T is the transverse momentum, and favored χ c1 production over χ c2 [4].…”

A measurement is presented of the relative prompt production rate of χc2 and χc1 with 4.6 fb−1 of data collected by the CMS experiment at the LHC in pp collisions at . The two states are measured via their radiative decays χc→J/ψ+γ, with the photon converting into an e+e− pair for J/ψ rapidity |y(J/ψ)|<1.0 and photon transverse momentum pT(γ)>0.5 GeV/c. The measurement is given for six intervals of pT(J/ψ) between 7 and 25 GeV/c. The results are compared to theoretical predictions.

“…The possibility of 1 S ½8 0 dominance and the J=c polarization puzzle are also discussed. DOI Nearly 20 years ago, the CDF Collaboration found a surprisingly large production rate of c 0 at high p T [1]. To solve the large discrepancy between data and theoretical predictions, the color-octet (CO) mechanism [2] was proposed based on nonrelativistic QCD (NRQCD) factorization [3].…”

We present a complete evaluation for J/ψ(ψ') prompt production at the Tevatron and LHC at next-to-leading order in nonrelativistic QCD, including color-singlet, color-octet, and higher charmonia feeddown contributions. The short-distance coefficients of 3P(J)([8]) at next-to-leading order are found to be larger than leading order by more than an order of magnitude but with a minus sign at high transverse momentum p(T). Two new linear combinations of color-octet matrix elements are obtained from the CDF data, and used to predict J/ψ production at the LHC, which agrees with the CMS data. The possibility of (1)S(0)([8]) dominance and the J/ψ polarization puzzle are also discussed.
