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 ...

Quantum gravity, fakeons and microcausality

Journal of High Energy Physics, 2018
We investigate the properties of fakeons in quantum gravity at one loop. The theory is described by a graviton multiplet, which contains the fluctuation h μν of the metric, a massive scalar ϕ and the spin-2 fakeon χ μν .

On-shell Matrix Elements of the EMT Trace in Gauge Theories and Heavy Quark Masses

Physics Letters B
We present a novel diagrammatic proof of the identity between the forward matrix element of the energy-momentum-tensor (EMT) trace operator over a single particle's on-shell state and its perturbative pole mass to any loop orders in perturbative gauge ...
