“…It should be mentioned that the spin-1 particle, different from the spin-1/2 one, has the tensor structure function b 1 . It triggers great interest [58][59][60][61][62]. The sum rule of this structure function is dxb 1 (x) = 0 [58].…”

We study ρ meson unpolarized generalized parton distributions based on a light-front constituent quark model where the quark-antiquark-meson vertex is constructed under the symmetric loop momentum convention. The form factors and some other low-energy observables of the ρ meson are calculated. Moreover, the contributions to the form factors and generalized parton distributions from the valence and nonvalence regimes are discussed and analyzed in detail. In the forward limit, the usual structure functions are estimated as well. In addition, by evolving the moments of the obtained structure functions to the scale of the lattice calculation, we give the factorization scale of our quark model. It is found that the present phenomenological model is reasonable to describe the general properties of ρ meson.

“…The expected luminosities are at least as large as those discussed here. If one can ensure that the nucleus stays intact, this would provide new means to study the GPDs of these light nuclei [43][44][45][46][47][48][49][50][51][52][53][54] .…”

Single-transverse-spin asymmetries in exclusive photo-production of J/ψ in ultra-peripheral collisions in the fixed-target mode at the LHC and in the collider mode at RHIC

We investigate the potentialities offered by the study of J/ψ exclusive photo-production in ultra-peripheral collisions at a fixed-target experiment using the proton and lead LHC beams (generically denoted as AFTER@LHC) on hydrogen targets and at RHIC in the collider mode. We compare the expected counting rates in both set-ups. Studying Single-Transverse-Spin Asymmetries (A N ) in such a process provides a direct path to the proton Generalised Parton Distribution (GPD) E g (x, ξ, t). We evaluate the expected precision on A N for realistic conditions with the LHCb detector in pH ↑ and PbH ↑ collisions. We also discuss prospects with polarised deuterium and helium targets in the case of AFTER@LHC.

“…A complete picture of polynomiality for spin-1 targets is desirable due to an emerging interest in the partonic structure of particular spin-1 targets, and hard exclusive reactions involving such targets. Generalized parton distributions of the deuteron [26][27][28][29][30][31][32][33][34][35], rho meson [36][37][38][39], phi meson [19], and photon [40][41][42] have been the subjects of theoretical studies. Deeply virtual Compton scattering from the deuteron has been performed at HERMES [43,44], and is a topic of interest at Jefferson Lab [45,46], as well as the proposed Electron Ion Collider [47].…”

Polynomiality sum rules for generalized parton distributions of spin-1 targets

We present the polynomiality sum rules for all leading-twist quark and gluon generalized parton distributions (GPDs) of spin-1 targets such as the deuteron nucleus. The sum rules connect the Mellin moments of these GPDs to polynomials in skewness parameter ξ, which contain generalized form factors as their coefficients. The decompositions of local currents in terms of generalized form factors for spin-1 targets are obtained as a by-product of this derivation. * wim.cosyn@ugent.be † afreese@anl.gov ‡ bernard.pire@polytechnique.edu

Study of deuteron generalized parton distribution functions and its tensor structure function

Abstract: The generalized parton distribution functions of deuteron are studied based on a phenomenological effective Lagrangian approach. The electric, magnetic and quadrupole form factors are estimated. Moreover, the tensor structure function of the deuteron is discussed.
