Title: Precision direct photon spectra at high energy and comparison to the 8 TeV ATLAS data

Abstract

The direct photon spectrum is computed to the highest currently available precision and compared to ATLAS data from 8 TeV collisions at the LHC. The prediction includes threshold resummation at next-to-next-to-next-to-leading logarithmic order through the program PeTeR, matched to next-to-leading fixed order with fragmentation effects using JetPhox and includes the resummation of leading-logarithmic electroweak Sudakov effects. Remarkably, improved agreement with data can be seen when each component of the calculation is added successively. This comparison demonstrates the importance of both threshold logs and electroweak Sudakov effects. Numerical values for the predictions are included.

Precision photon spectra for wino annihilation

Journal Article Baumgart, Matthew ; Cohen, Timothy ; Moulin, Emmanuel ; ... - Journal of High Energy Physics (Online)

We provide precise predictions for the hard photon spectrum resulting from neutral SU(2)W triplet (wino) dark matter annihilation. Our calculation is performed utilizing an effective field theory expansion around the endpoint region where the photon energy is near the wino mass. This has direct relevance to line searches at indirect detection experiments. We compute the spectrum at next-to-leading logarithmic (NLL) accuracy within the framework established by a factorization formula derived previously by our collaboration. This allows simultaneous resummation of large Sudakov logarithms (arising from a restricted final state) and Sommerfeld effects. Resummation at NLL accuracy shows good convergence of themore »« less

Measurements of integrated and differential cross sections for isolated photon pair production in $p p$ collisions at $\sqrt{s} = 8 TeV$ with the ATLAS detector

Journal Article Aaboud, M. ; Aad, G. ; Abbott, B. ; ... - Physical Review D

© 2017 CERN. A measurement of the production cross section for two isolated photons in proton-proton collisions at a center-of-mass energy of s=8 TeV is presented. The results are based on an integrated luminosity of 20.2 fb-1 recorded by the ATLAS detector at the Large Hadron Collider. The measurement considers photons with pseudorapidities satisfying |ηγ| < 1.37 or 1.56 < |ηγ| < 2.37 and transverse energies of respectively ET,1γ > 40 GeV and ET,2γ > 30 GeV for the two leading photons ordered in transverse energy produced in the interaction. The background due to hadronic jets and electrons is subtractedmore »« less

Resummed photon spectra for WIMP annihilation

Journal Article Baumgart, Matthew ; Cohen, Timothy ; Moult, Ian ; ... - Journal of High Energy Physics (Online)

We construct an effective field theory (EFT) description of the hard photon spectrum for heavy WIMP annihilation. This facilitates precision predictions relevant for line searches, and allows the incorporation of non-trivial energy resolution effects. Our framework combines techniques from non-relativistic EFTs and soft-collinear effective theory (SCET), as well as its multi-scale extensions that have been recently introduced for studying jet substructure. We find a number of interesting features, including the simultaneous presence of SCET _I and SCET _II modes, as well as collinear-soft modes at the electroweak scale. We derive a factorization formula that enables both the resummation of themore »« less

High precision predictions for exclusive VH production at the LHC

Journal Article Li, Ye ; Liu, Xiaohui - Journal of High Energy Physics (Online)

We present a resummation-improved prediction for pp → VH + 0 jets at the Large Hadron Collider. We focus on highly-boosted final states in the presence of jet veto to suppress the tt¯ background. In this case, conventional fixed-order calculations are plagued by the existence of large Sudakov logarithms α ⁿ _slog ^m(p ^veto _T/Q) for Q ~ m _V + m _H which lead to unreliable predictions as well as large theoretical uncertainties, and thus limit the accuracy when comparing experimental measurements to the Standard Model. In this work, we show that the resummation of Sudakov logarithms beyond themore »« less

Measurement of the inclusive isolated-photon cross section in pp collisions at $$\sqrt{s}$$ = 13 TeV using 36 fb ^-1 of ATLAS data

Journal Article Aad, G. ; Abbott, B. ; Abbott, D. C. ; ... - Journal of High Energy Physics (Online)

The differential cross section for isolated-photon production in pp collisions is measured at a centre-of-mass energy of 13 TeV with the ATLAS detector at the LHC using an integrated luminosity of 36.1 fb ^-1. The differential cross section is presented as a function of the photon transverse energy in different regions of photon pseudorapidity. The differential cross section as a function of the absolute value of the photon pseudorapidity is also presented in different regions of photon transverse energy. Next-to-leading-order QCD calculations from Jetphox and Sherpa as well as next-to-next-to-leading-order QCD calculations from Nnlojet are compared with the measurement, usingmore »« less
