20210128 Jan. 28, 2021 Pushed from the Precipice: Lattice Field Theory for Quantum Computers Hank Lamm, FNAL Roni Harnik Over the past five decades, Euclidean lattice field theory has matured into a broad program capable of making precise QCD predictions. While its success is undeniable, certain problems in real time and at finite density elude it due to sign problems. Early on, Feynman pointed out that many of these problems are naturally solvable on... More »

20210304 March 4, 2021 An unambiguous test of positivity at lepton colliders Jiayin Gu, U. Mainz Ying-Ying The diphoton channel at lepton colliders, e+e-  (mu+mu-) ->  gamma gamma, has a remarkable feature that the leading new physics contribution comes only from dimension-eight operators.  This contribution is subject to a set of positivity bounds,  derived from fundamental principles of Quantum Field Theory, such as unitarity, locality, analyticity and Lorentz invariance.  These positivity bounds are thus...
