Yangian Symmetry of Scattering Amplitudes and the Dilatation Operator in N = 4 Supersymmetric Yang-Mills Theory
(American Physical Society, 2015-09-30)It is known that the Yangian of PSU(2,2|4) is a symmetry of the tree-level S matrix of N=4 super Yang-Mills theory. On the other hand, the complete one-loop dilatation operator in the same theory commutes with the level-one ... -
Z boson production in Pb plus Pb collisions at root S-NN=5.02 TeV measured by the ATLAS experiment
(Elsevier, 2020-03-10)The production yield of Z bosons is measured in the electron and muon decay channels in Pb+Pb collisions at TeV with the ATLAS detector. Data from the 2015 LHC run corresponding to an integrated luminosity of 0.49 ... -

Zhang-Kawazumi invariants and superstring amplitudes
(2014-01-01)The four-graviton amplitude in Type IIB superstring theory is invariant under the S-duality group SL(2,Z) acting on the complex coupling T. This amplitude contains a sum of effective interactions D2pR4 with coefficients ...
