The Weyl double copy from twistor space
(2021-05-01)The Weyl double copy is a procedure for relating exact solutions in biadjoint scalar, gauge and gravity theories, and relates fields in spacetime directly. Where this procedure comes from, and how general it is, have until ... -
Pole skipping and Rarita-Schwinger fields
(American Physical Society, 2021-05-10)In this note we analyze the equations of motion of a minimally coupled Rarita-Schwinger field near the horizon of an anti–de Sitter-Schwarzschild geometry. We find that at special complex values of the frequency and momentum ... -

Search for Higgs boson production in association with a high-energy photon via vector-boson fusion with decay into bottom quark pairs at s = 13 TeV with the ATLAS detector
(Springer, 2021-03-01)A search is presented for the production of the Standard Model Higgs boson in association with a high-energy photon. With a focus on the vector-boson fusion process and the dominant Higgs boson decay into b-quark pairs, ... -
Quarter-BPS states, multi-symmetric functions and set partitions
(Springer, 2021-03-16)We give a construction of general holomorphic quarter BPS operators in N = 4 SYM at weak coupling with U(N) gauge group at finite N. The construction employs the Möbius inversion formula for set partitions, applied to ... -
pion : Simulating bow shocks and circumstellar nebulae
(Oxford University Press, 2021-03-19)Expanding nebulae are produced by mass-loss from stars, especially during late stages of evolution. Multidimensional simulation of these nebulae requires high resolution near the star and permits resolution that decreases ... -

Mass and density of the transiting hot and rocky super-Earth LHS 1478 b (TOI-1640 b)
(EDP Sciences, 2021-05)One of the main objectives of the Transiting Exoplanet Survey Satellite (TESS) mission is the discovery of small rocky planets around relatively bright nearby stars. Here, we report the discovery and characterization of ... -
Asymptotics of the D<sup>8</sup>R<sup>4</sup> genus-two string invariant
(2019-01-01)We continue our investigation of the modular graph functions and string invariants that arise at genus-two as coefficients of low energy effective interactions in Type II superstring theory. In previous work, the non-separating ... -
New modular invariants in N = 4 Super-Yang-Mills theory
(2021-04-01)We study modular invariants arising in the four-point functions of the stress tensor multiplet operators of the N = 4 SU(N) super-Yang-Mills theory, in the limit where N is taken to be large while the complexified Yang-Mills ... -
The classical double copy for M-theory from a Kerr-Schild ansatz for exceptional field theory
(2021-04-09)We construct the classical double copy formalism for M-theory. This extends the current state of the art by including the three form potential of eleven dimensional supergravity along with the metric. The key for this ... -

Search for single production of vector-like quarks decaying into Wb in pp collisions at root s=8 TeV with the ATLAS detector
(Springer, 2016-08-08)A search for singly produced vector-like Q quarks, where Q can be either a T quark with charge +2/3 or a Y quark with charge −4/3, is performed in proton–proton collisions recorded with the ATLAS detector at the LHC. The ... -
Measurement of the top quark mass in the t(t)over-bar -> dilepton channel from root s=8TeVATLAS data
(Elsevier, 2016-10-10)The top quark mass is measured in the channel () using ATLAS data recorded in the year 2012 at the LHC. The data were taken at a proton–proton centre-of-mass energy of and correspond to an integrated luminosity of about ... -
Measurement of the t(t)over-bar production cross-section using e mu events with b-tagged jets in pp collisions at root s=13 TeV with the ATLAS detector
(Elsevier, 2016-10-10)This paper describes a measurement of the inclusive top quark pair production cross-section () with a data sample of of proton–proton collisions at a centre-of-mass energy of , collected in 2015 by the ATLAS detector at ...
