چکیده
Working in the nonrelativistic-QCD factorization framework at next-to-leading order ${\ensuremath{\alpha}}_{s}$, we fit relevant color octet long-distance matrix elements of $\ensuremath{\psi}(2S)$ meson, $⟨{\mathcal{O}}^{\ensuremath{\psi}(2S)}({^{1}S}_{0}^{[8]})⟩$, $⟨{\mathcal{O}}^{\ensuremath{\psi}(2S)}({^{3}S}_{1}^{[8]})⟩$, and $⟨{\mathcal{O}}^{\ensuremath{\psi}(2S)}({^{3}P}_{0}^{[8]})⟩$, to 1001 data points upolarized polarized inclusive hadroproduction. We do four different fits, with filters on polarization low middle transverse momentum ${p}_{T}$. find that a successful description is only possible large low-${p}_{T}$ cut. Our results are one magnitude more precise than previous determinations these elements.

Inclusive Dijet Production at HERA: Direct Photon Cross Sections in Next-To-Leading Order QCD
We have calculated inclusive two-jet cross sections in next-to-leading order QCD for direct photoproduction in low Q2 ep collisions at HERA. Infrared and collinear singularities in real and virtual contributions are cancelled with the phase space slicing method. Analytical formulas for the different contributions giving the dependence on the slicing parameter are presented. Various oneand two-j...
متن کاملNext-to-Leading Order QCD Corrections to the Polarized Hadroproduction of Heavy Flavors
We present the complete next-to-leading order QCD corrections to the polarized hadroproduction of heavy flavors which soon will be studied experimentally in polarized pp collisions at the BNL RHIC in order to constrain the polarized gluon density ∆g. It is demonstrated that the dependence on unphysical renormalization and factorization scales is strongly reduced beyond the leading order. The se...
متن کاملQCD corrections to inclusive ∆ S = 1 , 2 transitions at the next - to - leading order
The 2–point functions for ∆S = 1 current-current and QCD-penguin operators, as well as for the ∆S = 2 operator, are calculated at the next-to-leading order. The calculation is performed in two different renormalization schemes for γ5, and the compatibility of the results obtained in the two schemes is verified. The scaleand scheme-invariant combinations of spectral 2–point functions and corresp...
متن کاملInclusive D∗ Production in Photon-Photon Collisions at Next-to-Leading Order QCD
The next-to-leading order cross section for the inclusive production of charm quarks in γγ collisions is calculated as a function of the transverse momentum pT and the rapidity y in approaches using massive or massless charm quarks. For the direct cross section we derive the massless limit from the massive theory with the result that this limit differs from the massless version with MS factoriz...
متن کاملThreshold corrections in bottom and charm quark hadroproduction at next-to-next-to-leading order
We calculate threshold soft-gluon corrections to total cross sections and transverse momentum distributions for bottom and charm quark production in fixed-target experiments, considering both pp and π−p interactions. We investigate the quality of the near threshold soft-gluon approximation at next-to-leading order (NLO) and calculate next-to-nextto-leading order (NNLO) corrections through next-...
