Hidden classical symmetry in quantum spaces at roots of unity : From qsphere to fuzzy sphere
(2000)We study relations between different kinds of noncommutative spheres which have appeared in the context of ADS/CFT correspondences recently, emphasizing the connections between spaces that have manifest quantum group ... 
Identification of high transverse momentum top quarks in pp collisions at √s= 8 TeV with the ATLAS detector
(Springer, 20160601)© 2016, The Author(s).This paper presents studies of the performance of several jetsubstructure techniques, which are used to identify hadronically decaying top quarks with high transverse momentum contained in largeradius ... 
Identities between modular graph forms
(Elsevier, 201801)This paper investigates the relations between modular graph forms, which are generalizations of the modular graph functions that were introduced in earlier papers motivated by the structure of the low energy expansion of ... 
Inelastic black hole scattering from charged scalar amplitudes
(Springer, 201803)We explain how the lowestorder classical gravitational radiation produced during the inelastic scattering of two Schwarzschild black holes in General Relativity can be obtained from a tree scattering amplitude in gauge ... 
The KerrSchild double copy in curved spacetime
(Springer, 201712)The double copy is a muchstudied relationship between scattering amplitudes in gauge and gravity theories, that has subsequently been extended to classical field solutions. In nearly all previous examples, the graviton ... 
Lagrangian formulation and symmetrical description of liquid dynamics
(American Physical Society, 201712)Theoretical description of liquids has been primarily based on the hydrodynamic approach and its generalization to the solidlike regime. We show that the same liquid properties can be derived starting from solidlike ... 
Matching the D 6ℛ4 interaction at twoloops
(201501)The coefficient of the D6R4 interaction in the low energy expansion of the twoloop fourgraviton amplitude in type II superstring theory is known to be proportional to the integral of the ZhangKawazumi (ZK) invariant ... 
Measurement of D*<sup>±</sup>, D<sup>±</sup> and D<inf>s</inf><sup>±</sup> meson production cross sections in pp collisions at s√=7 TeV with the ATLAS detector
(20160601)© 2016 The Authors.The production of D*±, D± and Ds± charmed mesons has been measured with the ATLAS detector in pp collisions at s=7 TeV at the LHC, using data corresponding to an integrated luminosity of 280 nb1. The ... 
Measurement of the angular coefficients in Zboson events using electron and muon pairs from data taken at √s = 8 TeV with the ATLAS detector
(20160801)© 2016, The Author(s).The angular distributions of DrellYan charged lepton pairs in the vicinity of the Zboson mass peak probe the underlying QCD dynamics of Zboson production. This paper presents a measurement of the ... 
Measurement of the charge asymmetry in highly boosted topquark pair production in √s=8 TeV pp collision data collected by the ATLAS experiment
(20160510)© 2016 CERN for the benefit of the ATLAS Collaboration.In the pp→tt process the angular distributions of top and antitop quarks are expected to present a subtle difference, which could be enhanced by processes not included ... 
Measurement of the dependence of transverse energy production at large pseudorapidity on the hardscattering kinematics of protonproton collisions at √s=2.76 TeV with ATLAS
(20160510)© 2016 CERN for the benefit of the ATLAS Collaboration.The relationship between jet production in the central region and the underlyingevent activity in a pseudorapidityseparated region is studied in 4.0 pb1 of s=2.76 ... 
Measurement of the inclusive isolated prompt photon cross section in pp collisions at s=8TeV with the ATLAS detector
(20160801)© 2016, The Author(s).Abstract: A measurement of the cross section for the inclusive production of isolated prompt photons in protonproton collisions at a centreofmass energy of s=8 TeV is presented. The measurement ... 
Measurement of the neutral D meson mixing parameters in a timedependent amplitude analysis of the D0 →π+ππ0 decay
(20160628)© 2016 American Physical Society.We perform the first measurement on the D0D0 mixing parameters using a timedependent amplitude analysis of the decay D0→π+ππ0. The data were recorded with the BABAR detector at centerofmass ...

Microscopic unitary description of tidal excitations in highenergy stringbrane collisions
(20131114)The eikonal operator was originally introduced to describe the effect of tidal excitations on highergenus elastic string amplitudes at high energy. In this paper we provide a precise interpretation for this operator ... 
Modular graph functions
(International Press of Boston, Inc, 2017)In earlier work we studied features of nonholomorphic modular functions associated with Feynman graphs for a conformal scalar field theory on a twodimensional torus with zero external momenta at all vertices. Such ...

New Fermionic Soft Theorems for Supergravity Amplitudes
(American Physical Society, 201507)Soft limits of a massless S matrix are known to reflect the symmetries of the theory. In particular, for theories with Goldstone bosons, the doublesoft limit of scalars reveals the coset structure of the vacuum manifold. ...
