Production of Very Massive Higgs Bosons

open access: yesPhysics Letters B, 1984
Abstract We compare Higgs boson production mechanisms at multi-TeV hadronic colliders. In addition to the previously investigated processes gluon + gluon → H and q q → V ∗ → VH ( V = W, Z ) , we consider Higgs boson formation by pairs of virtual W's or Z's, a process analogous to two-photon collisions in e+e− scattering.

Enhanced di-Higgs production in the two Higgs doublet model [PDF]

open access: yesJournal of High Energy Physics, 2019
Abstract We show that the rate for di-Higgs production at the LHC can be enhanced by a factor as large as 25 compared to the Standard Model value in the two Higgs doublet model, while being consistent with the known properties of the observed Higgs boson h.

Analytic approximations of 2 → 2 processes with massive internal particles

open access: yesJournal of High Energy Physics, 2023
We consider two-loop corrections to 2 → 2 scattering processes with massive particles in the final state and massive particles in the loop. We discuss the combination of analytic expansions in the high-energy limit and for small Mandelstam variable t ...

Probing the symmetric Higgs portal with di-Higgs boson production [PDF]

open access: yesPhysical Review D, 2019
A coupling of a scalar, charged under an unbroken global U(1) symmetry, to the Standard Model via the Higgs portal is one of the simplest gateways to a dark sector. Yet, for masses $m_{S}\geq m_{H}/2$ there are few probes of such an interaction. In this note we evaluate the sensitivity to the Higgs portal coupling of di-Higgs boson production at the ...

Menopause and vascular endothelial health: Is it all about the oestrogen? [PDF]

open access: yesExp Physiol
Abstract Cardiovascular disease (CVD) is a leading cause of mortality in women, and CVD risk is accelerated during the menopause transition. This acceleration has traditionally been attributed to the hallmark decline in oestradiol with menopause. However, the menopause transition is also characterized by changes in other sex hormones that exert effects

Deep learning to improve the sensitivity of Di-Higgs searches in the 4b channel

open access: yesJournal of High Energy Physics
The study of di-Higgs events, both resonant and non-resonant, plays a crucial role in understanding the fundamental interactions of the Higgs boson.

A Perspective on Interactive Theorem Provers in Physics

open access: yesAdvanced Science, EarlyView.
Into an interactive theorem provers (ITPs), one can write mathematical definitions, theorems and proofs, and the correctness of those results is automatically checked. This perspective goes over the best usage of ITPs within physics and motivates the open‐source community run project PhysLean, the aim of which is to be a library for digitalized physics

Constraint on the total width of the Higgs boson from Higgs boson and four-top-quark measurements in pp collisions at s = 13 TeV with the ATLAS detector

open access: yesPhysics Letters B
This Letter presents a constraint on the total width of the Higgs boson (ΓH) using a combined measurement of on-shell Higgs boson production and the production of four top quarks, which involves contributions from off-shell Higgs boson-mediated processes.

Off-shell Higgs production at the LHC as a probe of the trilinear Higgs coupling

open access: yesJournal of High Energy Physics, 2022
In the context of the Standard Model effective field theory (SMEFT) we examine the constraints on the trilinear Higgs coupling that originate from off-shell Higgs production in proton-proton collisions.

A Micropeptide Component of the OGDH Complex Modulates ATP Production in the TCA Cycle

open access: yesAdvanced Science, EarlyView.
This study identified a mitochondrial micropeptide encoded by a non‐canonical open reading frame (alt‐ORF) within the CTSB gene. This micropeptide named APPM (ATP production‐promoting micropeptide) is a novel component of the OGDHc complex in the TCA cycle. APPM localizes to the inner mitochondrial membrane and directly binds to OGDH, the E1 subunit of
