Measuring the gluon spin in protons through η central production
نویسنده
چکیده
The investigation of a proposed glueball filter in proton-proton collisions led us to show that its action is in fact easily understood in terms of kinematics. While the procedure proposed stays of interest in reducing background when looking for centrally produced resonances of specified spin and parity, we stress that it can be put to advantage in giving access to the polarization of gluons in the inital protons.

Central pseudoscalar production in pp scattering and the gluon contribution to the proton spin
Central pseudoscalar production in pp scattering is suppressed at small values of Q ⊥ , where Q is defined as the difference between the momenta transferred from the two protons. Such a behaviour is expected if the production occurs through the fusion of two vectors. Photon exchange could provide the dominant contribution here, but we argue that an extension of the experiment could probe the gl...

متن کاملProton spin structure and the axial U(1) problem
and the large mass of the η meson point to large violations of OZI in the flavour-singlet J = 1 channel [2–4]. The strong (QCD) axial anomaly is central to theoretical explanations of the small value of g (0) A |pDIS (about 50% of the OZI value 0.6) and the large η mass. In this paper we review the role of the anomaly in the spin structure of the proton and highlight the interplay between the p...
متن کاملOn the possibility of measuring the gluon distribution in proton with “γ + jet” events at LHC
The numbers of the “γ + jet” events suitable for a determination of the gluon distribution function f g (x,Q ) in a proton at the LHC for various intervals of x and Q are estimated. The contributions of different background sources are studied. The values of discrimination powers between quark and gluon jets as well as between a single photon and the products of π, η, ω and K s mesons decaying ...
متن کاملPolarized Gluon Distribution Function from η′ Production
Using the recently proposed ggη effective vertex, we investigate the production of η from gluon fusion in polarized pp collisions. We show that by measuring ALL in η ′ production, one can extract the polarized gluon distribution ∆G(x,Q) at Q ∼ 1GeV and in a wide range of x.
