“…At that time, it was suggested a resummation formula for the case of zero rapidity. Very recently, thanks to the analysis of the full NLO calculation of the Drell-Yan rapidity distribution, it has been shown [8], that the result given in [7] is valid at NLL for all rapidities.…”

We present a derivation of the threshold resummation formula for the Drell-Yan rapidity distribution. Our argument is valid for all values of rapidity and to all orders in perturbative QCD and can be applied to all Drell-Yan processes in a universal way, i.e. both for the production of a virtual photon γ * and the production of a vector boson W ± , Z 0 . We show that for the fixedtarget experiment E866/NuSea used in current parton fits, the NLL resummation corrections are comparable to NLO fixed-order corrections and are crucial to obtain agreement with the data.

“…The high scale set by the W boson mass makes it possible to extract quark and anti-quark polarizations from inclusive lepton single-spin asymmetries in W boson production with minimal theoretical uncertainties, as higher order and sub-leading terms in the perturbative QCD expansion are suppressed [34,35,36,37].…”

We discuss some recent developments concerning the nucleon's helicity parton distribution functions: New preliminary data from jet production at RHIC suggest for the first time a non-vanishing polarization of gluons in the nucleon. SIDIS measurements at COMPASS provide better constraints on the strange and light sea quark helicity distributions. Single-longitudinal spin asymmetries in W -boson production have been observed at RHIC and will ultimately give new insights into the light quark and anti-quark helicity structure of the nucleon.

“…We will assume knowledge of the resummed results in N -Mellin space, both at the level of inclusive crosssections [21][22][23] and rapidity distributions [24,25,6], and we will concentrate on the ambiguities related to their definition. First, we briefly review some prescriptions introduced in order to deal with the divergent nature of the perturbative expansion for resummed quantities.…”

Soft gluon resummation of Drell–Yan rapidity distributions: Theory and phenomenology

We examine critically the theoretical underpinnings and phenomenological implications of soft gluon (threshold) resummation of rapidity distributions at a hadron collider, taking Drell-Yan production at the Tevatron and the LHC as a reference test case. First, we show that in perturbative QCD soft gluon resummation is necessary whenever the partonic (rather the hadronic) center-of-mass energy is close enough to threshold, and we provide tools to assess when resummation is relevant for a given process. Then, we compare different prescriptions for handling the divergent nature of the series of resummed perturbative corrections, specifically the minimal and Borel prescriptions. We assess the intrinsic ambiguities of resummed results, both due to the asymptotic nature of their perturbative expansion, and to the treatment of subleading terms. Turning to phenomenology, we introduce a fast and accurate method for the implementation of resummation with the minimal and Borel prescriptions using an expansion on a basis of Chebyshev polynomials. We then present results for W and Z production as well as both high-and low-mass dilepton pairs at the LHC, and show that soft gluon resummation effects are generally comparable in size to NNLO corrections, but sometimes affected by substantial ambiguities.
