T T ¯ $$ T\overline{T} $$ deformations and the width of fundamental particles

Abstract We provide a simple geometric meaning for deformations of so-called T T ¯ $$ T\overline{T} $$ type in relativistic and non-relativistic systems. Deformations by the cross products of energy and momentum currents in integrable quantum field theories are known to modify the thermodynamic Beth...
