Existence and Construction of Galilean invariant Theories
Benjamin Grinstein, Sridip Pal
We prove a no-go theorem for the construction of a Galilean boost invariant and anisotropic scale invariant field theory with a finite dimensional basis of fields. Two poi…
On Limit Cycles in Supersymmetric Theories
Jean-François Fortin, Benjamín Grinstein, Christopher W. Murphy +1
Contrary to popular belief conformality does not require zero beta functions. This follows from the work of Jack and Osborn, and examples in non-supersymmetric theories were recent…
Lee-Wick Theories at High Temperature
Bartosz Fornal, Benjamin Grinstein, Mark B. Wise
An extension of the standard model, the Lee-Wick standard model, based on ideas of Lee and Wick was recently introduced. It does not contain quadratic divergences in the Higgs mass…
Causality as an emergent macroscopic phenomenon: The Lee-Wick O(N) model
Benjamin Grinstein, Donal O'Connell, Mark B. Wise
In quantum mechanics the deterministic property of classical physics is an emergent phenomenon appropriate only on macroscopic scales. Lee and Wick introduced Lorentz invariant qua…
