Tensor bounds on the hidden universe

Journal of High Energy Physics, 2018
During single clock inflation, hidden fields (i.e. fields coupled to the inflaton only gravitationally) in their adiabatic vacua can ordinarily only affect observables through virtual effects.

Quantum field theory with no zero-point energy

Journal of High Energy Physics, 2018
Traditional quantum field theory can lead to enormous zero-point energy, which markedly disagrees with experiment. Unfortunately, this situation is built into conventional canonical quantization procedures.

The Z penguin in generic extensions of the Standard Model

Journal of High Energy Physics, 2019
Precision flavour observables play an important role in the interpretation of results at the LHC in terms of models of new physics. We present the result for the one-loop Z penguin in generic extensions of the standard model which exhibit exact ...

Asymptotic behavior of diagram classes

Journal of High Energy Physics
Perturbative expansions in quantum field theory are typically asymptotic, with large-order growth driven by instantons (factorial proliferation of diagrams) and renormalons (factorial growth from momentum integrations).
