Abstract: A bstractWe present an implementation of the relativistic three-particle quantization condition including both s- and d-wave two-particle channels. For this, we develop a systematic expansion of the three-particle K matrix, K$$ \mathcal{K} $$df,3, about threshold,… read more here.

Abstract: We present a simplified derivation of the relativistic three-particle quantization condition for identical, spinless particles described by a generic relativistic field theory satisfying a $\mathbb Z_2$ symmetry. The simplification is afforded by using a three-particle… read more here.

Abstract: Partial quenching allows one to consider correlation functions and amplitudes that do not arise in the corresponding unquenched theory. For example, physical s-wave pion scattering can be decomposed into I = 0 and 2 amplitudes,… read more here.
