Precision QCD phenomenology of exotic spin-2 search at the LHC

Abstract

The complete next-to-next-to leading order (NNLO) QCD correction matched with next-to-next-to leading logarithm (NNLL) has been studied for Drell-Yan production through spin-2 particle at the Large hadron collider (LHC). We consider generic spin-2 particle which couples differently to the quarks and the gluons (non-universal scenario). The threshold enhanced analytical coefficient has been obtained up to third order exploiting the universality of the soft function as well as the process dependent form factors at the same order. We performed a detailed phenomenological analysis and give prediction for the 13 TeV LHC for the search of such BSM signature. We found that the matched correction at the second order gives sizeable corrections over wide range of invariant mass of the lepton pair. The scale variation also stabilizes at this order and reduces to 4%. As a by-product we also provide ingredients for third order soft-virtual (SV) prediction as well as resummation and study the impact on LHC searches.
