“…In this model pomeron exchange is effectively treated as the exchange of a rank-2 symmetric tensor. In [19] we show that the tensor pomeron is consistent with the STAR pp elastic scattering data [20]. In Ref.…”

“…from the TOTEM experiment [6], call for a revision [7]. However, the accuracy of existing polarized high energy experimental data [8][9][10][11] was insufficient to identify a Pomeron contribution, if any, to the pp spin-dependent amplitudes.In this Letter, we report new measurements of the single spin A N (t) and double spin A NN (t) analyzing powers in the small angle elastic collision of RHIC's polarized proton beams with Polarized Atomic Hydrogen Gas Jet Target [15](HJET) at √ s = 13.76 and 21.92 GeV. The precision has been significantly improved compared to previous HJET publications [9,10] and this has allowed us to not only isolate hadronic spin-flip amplitudes but also to incorporate spin dependence in a Regge pole anal-…”

“…Moreover, the CNI analyzing power A N rather weekly depends on the beam momentum. Recently, it has been precisely measured at RHIC in BNL [12][13][14] for various beam momenta, some of which are within and some above the momentum range of interest for SPASCHARM. The A N maximum of ∼ (4-4.5)% is reached at −t 0.003 (GeV/c) 2 , and its average for the interval 0.002 < −t < 0.05 (GeV/c) 2 , weighted with the cross section, can conservatively be estimated at ∼3%.…”
