Quantum corrections to the primordial tensor spectrum: open EFTs & Markovian decoupling of UV modes
Journal of High Energy Physics, 2022 Perturbative quantum corrections to primordial power spectra are important for testing the robustness and the regime of validity of inflation as an effective field theory.

A cosmological signature of the SM Higgs instability: gravitational waves [PDF]
Journal of Cosmology and Astroparticle Physics, 2018 A fundamental property of the Standard Model is that the Higgs potential becomes unstable at large values of the Higgs field. For the current central values of the Higgs and top masses, the instability scale is about 1011 GeV and therefore not accessible

Measuring the quartic Higgs self-coupling at a multi-TeV muon collider [PDF]
Journal of High Energy Physics, 2020 Measuring the shape of the Higgs boson potential is of paramount importance, and will be a challenging task at current as well as future colliders. While the expectations for the measurement of the trilinear Higgs self-coupling are rather promising, an ...

Physics Letters B, 1984 Abstract The binding of two Higgs bosons is calculated using the N/D method. Bound states occur for m H > 1.3 TeV. The binding is weak and even when m H = 2 TeV the binding energy is only about 150 GeV. Higgs bosons with masses in the TeV range have widths comparable to their masses. Accordingly, so do their bound states.

Higgs Mode in Superconductors [PDF]
Annual Review of Condensed Matter Physics, 2019 When the continuous symmetry of a physical system is spontaneously broken, two types of collective modes typically emerge: the amplitude and the phase modes of the order-parameter fluctuation.

Single charged Higgs boson production at next generation linear colliders [PDF]
, 2000 We study the single production of charged Higgs bosons in e+e- collisions, chiefly in the Minimal Supersymmetric Standard Model. Our analysis complements foregoing studies of the pair production channel especially in regions where the kinematic ...

Journal of High Energy Physics, 2023 Abstract We present a novel construction for a Higgs-VEV sensitive (HVS) operator, which can be used as a trigger operator in cosmic selection models for the electroweak hierarchy problem. Our operator does not contain any degrees of freedom charged under the SM gauge symmetries, leading to reduced tuning in the resulting models ...

Large gauge effects and the structure of amplitudes
Journal of High Energy Physics, 2023 We show that large gauge transformations modify the structure of momentum conservation leading to non-vanishing three-point amplitudes in a simple toy model of a gravitational wave event.
