Continuity and Semileptonic Form Factors

Andrew Kobach

Small changes in the masses of massive external scattering states should correspond to small changes in the non-perturbative parameterization of form factors in quantum field theor…

Baryon Number, Lepton Number, and Operator Dimension in the SMEFT with Flavor Symmetries

Andreas Helset, Andrew Kobach

For a large set of flavor symmetries, the lowest-dimensional baryon- or lepton-number violating operators in the Standard Model effective field theory (SMEFT) with flavor symmetry…

Reparameterization Invariant Operator Basis for NRQED and HQET

Andrew Kobach, Sridip Pal

We discuss how reparameterization invariance connects a rotationally-invariant heavy particle effective theory with a single fermion to a Lorentz-invariant theory. Using Hilbert-se…

Conformal Structure of the Heavy Particle EFT Operator Basis

Andrew Kobach, Sridip Pal

An operator basis of an effective theory with a heavy particle, subject to external gauge fields, is spanned by a particular kind of neutral scalar primary of the nonrelativistic c…

Neutrino Oscillation Measurements Computed in Quantum Field Theory

Andrew Kobach, Aneesh V. Manohar, John McGreevy

We perform a calculation in quantum field theory of neutrino oscillation probabilities, where we include simultaneously the source, detector, and neutrino fields in the Hamiltonian…

Hilbert Series and Operator Basis for NRQED and NRQCD/HQET

Andrew Kobach, Sridip Pal

We use a Hilbert series to construct an operator basis in the expansion of a theory with a nonrelativistic heavy fermion in an electromagnetic (NRQED) or color gauge field (N…
