Breakdown of the naive parton model in super-weak scale collisions
Matthew Baumgart, Ozan Erdoğan, Ira Z. Rothstein +1
In this letter we show that for observables which involve the measurement of weak charge in final states in hadronic collisions, the standard parton model picture breaks down at sc…
From Scattering Amplitudes to Classical Potentials in the Post-Minkowskian Expansion
Clifford Cheung, Ira Z. Rothstein, Mikhail P. Solon
We combine tools from effective field theory and generalized unitarity to construct a map between on-shell scattering amplitudes and the classical potential for interacting spinles…
Manifestly Soft Gauge Invariant Formulation of vNRQCD
Ira Z. Rothstein, Prashant Shrivastava, Iain W. Stewart
Homogeneous power counting in Non-Relativistic QCD (NRQCD) implies the simultaneous existence of both soft and ultrasoft gluons. In the velocity renormalization group (vNRQCD) form…
Wilsonian effective field theory of 2D van Hove singularities
Anton Kapustin, Tristan McKinney, Ira Z. Rothstein
We study 2D fermions with a short-range interaction in the presence of a van Hove singularity. It is shown that this system can be consistently described by an effective field theo…
