“…We recall that, in the context of the LHC, an experimental analysis (done with PYTHIA) [24] showed that, for an integrated luminosity of 10 pb À1 , the expected number of events is about 6000 for Á ¼ 8 and 3500 for Á ¼ 9 (with R ' 1 and Q ' 50 GeV). These represent large enough yields for the cross section to be measured.…”

We study the production of Mueller-Navelet jets at hadron colliders in the Balitsky-Fadin-KuraevLipatov framework. We show that a measurement of the relative azimuthal angle ÁÈ between the jets can provide a good testing ground for corrections due to next-leading logarithms (NLL). Besides the wellknown azimuthal decorrelation with increasing rapidity interval Á between the jets, we propose to also measure this effect as a function of R ¼ k 2 =k 1 , the ratio between the jet transverse momenta. Using renormalization-group improved NLL kernel, we obtain predictions for d=dÁdRdÁÈ. We analyze NLL-scheme and renormalization-scale uncertainties, and energy-momentum conservation effects, in order to motivate a measurement at the Tevatron and the LHC.

“…in the rest frame of the ion; in this case we have q 2 = Q 2 , so that written covariantly this corresponds to the F (Q 2 ) which appears in (8). In impact parameter space, the coherent amplitude is given by a convolution of the transverse proton density within the ion, and the amplitude for photon emission from individual protons; hence in transverse momentum space we simply multiply by the corresponding form factor.…”

“…where '+' signs are used to denote the presence of large rapidity gaps, separating the system X from the intact outgoing hadrons h. This simple signal is associated with a broad and varied phenomenology, from low energy QCD to high energy BSM physics, see [1][2][3][4][5][6] for reviews. Consequently an extensive experimental programme is planned and ongoing at the LHC, with dedicated proton tagging detectors installed and collecting data in association with both ATLAS and CMS [7,8], while multiple measurements using rapidity gap vetoes have been made by LHCb and ALICE. CEP may proceed via either QCD or photon-induced interactions, see Fig.…”

Exclusive LHC physics with heavy ions: SuperChic 3

2019

We present results of the updated SuperChic 3 Monte Carlo event generator for central exclusive production. This extends the previous treatment of proton–proton collisions to include heavy ion (pA and AA) beams, for both photon and QCD-initiated production, the first time such a unified treatment of exclusive processes has been presented in a single generator. To achieve this we have developed a theory of the gap survival factor in heavy ion collisions, which allows us to derive some straightforward results about the A scaling of the corresponding cross sections. We compare against the recent ATLAS and CMS measurements of light-by-light scattering at the LHC, in lead-lead collisions. We find that the background from QCD-initiated production is expected to be very small, in contrast to some earlier estimates. We also present results from new photon-initiated processes that can now be generated, namely the production of axion-like particles, monopole pairs and monopolium, top quark pair production, and the inclusion of W loops in light-by-light scattering.

“…including the full effect of both the subprocess cross sectionσ(gg → X) and secondary rescatterings on the distributions. This is clearly important if we are to confront these aspects of the model with existing and future data, in particular in the presence of the proposed forward proton detectors [20,23,72]. More specifically, we recall that a detailed study of the p ⊥ and azimuthal distributions of the outgoing protons would allow us to probe the different available models for soft diffraction, see for instance [42].…”

Standard candle central exclusive processes at the Tevatron and LHC

et al. 2010

Central exclusive production (CEP) processes in high-energy proton -(anti)proton collisions offer a very promising framework within which to study both novel aspects of QCD and new physics signals. Among the many interesting processes that can be studied in this way, those involving the production of heavy (c, b) quarkonia and γγ states have sufficiently well understood theoretical properties and sufficiently large cross sections that they can serve as 'standard candle' processes with which we can benchmark predictions for new physics CEP at the CERN Large Hadron Collider. Motivated by the broad agreement with theoretical predictions of recent CEP measurements at the Fermilab Tevatron, we perform a detailed quantitative study of heavy quarkonia (χ and η) and γγ production at the Tevatron, RHIC and LHC, paying particular attention to the various uncertainties in the calculations. Our results confirm the rich phenomenology that these production processes offer at present and future high-energy colliders.
