“…In this paper, we report on a calculation of BFKL effects in the leading order approximation at t = t min . We find that the leading logarithmic (LL) BFKL resummation greatly enhances the cross section, as previously observed in other reactions [8,[12][13][14]. In addition, we estimate next-to-leading logarithmic (NLL) effects by the use of the BLM scale fixing prescription [15] supplemented by the resummation scheme of Refs.…”

We calculate the leading order BFKL amplitude for the exclusive diffractive process γ *L in the forward direction, which can be studied in future high energy e + e − linear colliders. The resummation effects are very large compared to the fixed-order calculation. We also estimate the next-toleading logarithmic corrections to the amplitude by using a specific resummation of higher order effects and find a substantial growth with energy, but smaller than in the leading logarithmic approximation.

“…As discussed in [14] this constant is related to the average attained values of z 1,2 in the process. The authors of [14] chose a very small value c Y = 0.01. We estimate the corresponding effect more conservatively and choose c Y = 0.3 for the cross section predictions shown below (see also [13]).…”

“…It is well known [54][55][56][57] that in the BLM approach, applied to semi-hard processes, we need to perform a finite renormalization from the MS to the physical MOM scheme, whose definition is related to the 3-gluon vertex being a key ingredient of the BFKL resummation. So, we have…”

The study of the inclusive production of a pair of charged light hadrons (a "dihadron" system) featuring high transverse momenta and well separated in rapidity represents a clear channel for the test of the BFKL dynamics at the Large Hadron Collider (LHC). This process has much in common with the well-known Mueller-Navelet jet production; however, hadrons can be detected at much smaller values of the transverse momentum than jets, thus allowing to explore an additional kinematic range, supplementary to the one studied with Mueller-Navelet jets. Furthermore, it makes it possible to constrain not only the parton densities (PDFs) for the initial proton, but also the parton fragmentation functions (FFs) describing the detected hadron in the final state. Here, we present the first full NLA BFKL analysis for cross sections and azimuthal angle correlations for dihadrons produced in the LHC kinematic ranges. We make use of the BrodskyLapage-Mackenzie optimization method to set the values of the renormalization scale and study the effect of choosing different values for the factorization scale. We also gauge the uncertainty coming from the use of different PDF and FF parametrizations.

“…High-energy QCD effects in the coupling of PI processes to jets, for low but finite photon virtualities, have been studied in Refs. [27][28][29][30][31][32]. Some of the PDF collaborations have released sets that include the photon as an additional parton inside the hadron: MRST2004QED [33], NNPDF2.3QED [34] and CT14QED [35].…”

Photon-initiated production of a dilepton final state at the LHC: Cross section versus forward-backward asymmetry studies

et al. 2017

We explore the effects of Photon Induced (PI) production of a dilepton final state in the Large Hadron Collider environment. Using QED Parton Distribution Function (PDF) sets we can treat the photons as real partons inside the protons and compare their yield directly to that of the DrellYan (DY) process. In particular, we concentrate on an error analysis of the two mechanisms. In order to do so, we use the NNPDF set, which comes with a set of replicas to estimate the systematic PDF error, and the CT14 set. On the one hand, we find that the PI contribution becomes dominant over DY above a dilepton invariant mass of 3 TeV. On the other hand, the PI predictions are affected by a large uncertainty coming from the QED PDFs, well above the one affecting the DY mode. We assess the impact of these uncertainties in the context of resonant and non-resonant searches for a neutral massive vector boson (Z ) through the differential cross section and ForwardBackward Asymmetry (AFB) observables as a function of the dilepton invariant mass. While the former is subject to the aforementioned significant residual errors the latter shows the systematic error cancellation expected (recall that AFB is a ratio of cross sections) even in presence of PI contributions, so that the recently emphasized key role played by AFB as a valid tool for both Z discovery and interpretation in both resonant and non-resonant mode is further consolidated. *
