Measurement of cross sections and couplings of the Higgs Boson in bosonic decay channels with the ATLAS detector

open access: yesEPJ Web of Conferences, 2018
After the discovery of the Higgs boson, the measurement of its properties are of particular importance. In this paper, measurement of the cross sections and couplings of the Higgs boson in bosonic decay channels with the ATLAS detector are presented ...

Signature of pseudo Nambu–Goldstone Higgs boson in its decay

open access: yesPhysics Letters B, 2019
If the Higgs boson is a pseudo Nambu–Goldstone boson (PNGB), the hZγ contact interaction induced by the O(p4) invariants of the non-linear sigma model is free from its nonlinearity effects.

Contingent Prizes in Dynamic Contests

open access: yesThe RAND Journal of Economics, Volume 56, Issue 4, Page 476-493, Winter 2025.
ABSTRACT Firms and government agencies increasingly use online contests to find solutions to problems. These contests allow players to make multiple attempts, and their progress is tracked on a real‐time public leaderboard. Although the contests are dynamic, contest sponsors miss the opportunity to dynamically shape players' incentives, as they award ...

The Higgs boson

open access: yes, 2016
Abstract This chapter starts with a simple introduction to gauge invariance and spontaneous symmetry breaking. An elementary introduction to Lagrangians in classical and quantum mechanics is given. A simplified description of the Higgs mechanism for electroweak symmetry breaking is presented in terms of Lagrangians.

Search for nonresonant Higgs boson pair production in the b b ¯ b b ¯ $$ \mathrm{b}\overline{\mathrm{b}}\mathrm{b}\overline{\mathrm{b}} $$ final state at s $$ \sqrt{s} $$ = 13 TeV

open access: yesJournal of High Energy Physics, 2019
Results of a search for nonresonant production of Higgs boson pairs, with each Higgs boson decaying to a b b ¯ $$ \mathrm{b}\overline{\mathrm{b}} $$ pair, are presented. This search uses data from proton-proton collisions at a centre-of-mass energy of 13

Unification of Conformal and Fuzzy Gravities With Internal Interactions Resulting in SO(10) and a Possible Probe Through Stochastic Gravitational Wave Background

open access: yesFortschritte der Physik, Volume 73, Issue 9-10, October 2025.
Abstract The unification of conformal and fuzzy gravities with internal interactions is based on the facts that i) the tangent group of a curved manifold and the manifold itself do not necessarily have the same dimensions and ii) both gravitational theories considered here have been formulated in a gauge theoretic way.

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.

Holomorphic field theories and higher algebra

open access: yesBulletin of the London Mathematical Society, Volume 57, Issue 10, Page 2903-2974, October 2025.
Abstract Aimed at complex geometers and representation theorists, this survey explores higher dimensional analogs of the rich interplay between Riemann surfaces, Virasoro and Kac‐Moody Lie algebras, and conformal blocks. We introduce a panoply of examples from physics — field theories that are holomorphic in nature, such as holomorphic Chern‐Simons ...

The Curious Concept That Almost Nobody Seemed to Care About at First: Virtual Particles in the Post‐War Period**

open access: yesBerichte zur Wissenschaftsgeschichte, Volume 48, Issue 1-2, Page 143-162, August 2025.
Abstract Short‐lived, unobservable, and not subject to the usual rules of conservation of energy and momentum, virtual particles—an integral part of the conceptual framework of quantum field theory (QFT)—exhibit a number of curious characteristics which, in recent decades, have in part fueled important discussions about their ontological status ...

Measurement and interpretation of differential cross sections for Higgs boson production at s=13TeV

open access: yesPhysics Letters B, 2019
Differential Higgs boson (H) production cross sections are sensitive probes for physics beyond the standard model. New physics may contribute in the gluon-gluon fusion loop, the dominant Higgs boson production mechanism at the LHC, and manifest itself ...
