The Aharonov-Anandan geometric phase is generalized to non-unitary evolution, and is shown to be always real. By using a counter-example, which is exactly solvable, it is shown that Berry's geometric phase is not always the adiabatic limit of Aharonov-Anandan's geometric phase for a non-Hermitian dr
I present analytic expressions for coefficients of the master integrals of a general one-loop amplitude. The functions are derived from D-dimensional unitarity cuts with tree-level input.
## Abstract In this talk we present a new method to do reduction for one‐loop amplitudes using unitarity cuts. Our method uses the tree‐level amplitudes as input so it is a very efficient method.
