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.

Neutrinoloser Doppelbetazerfall: Der Gral der Neutrinophysik

open access: yesPhysik in unserer Zeit, Volume 56, Issue 3, Page 132-137, May 2025.
Die Entschlüsselung der Neutrinoeigenschaften ist auch siebzig Jahre nach ihrer Entdeckung noch nicht abgeschlossen. Es wäre eine spektakuläre Entdeckung, sollten Neutrinos ihre eigenen Antiteilchen sein und sich folglich als Majorana‐Teilchen entpuppen. Mehrere Experimente untersuchen diese Möglichkeit.

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

An Algebraic Roadmap of Particle Theories

open access: yesAnnalen der Physik, Volume 537, Issue 4, April 2025.
The SO(10) grand unified theory, the Georgi–Glashow SU(5) grand unified theory, the Pati–Salam model, the Left–Right Symmetric model, and the Standard model have been studied extensively since the 1970s. Recasting these models in a division algebraic language elucidates how they are each in fact connected.

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 ...

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.

Constraints on anomalous Higgs boson couplings using production and decay information in the four-lepton final state

open access: yesPhysics Letters B, 2017
A search is performed for anomalous interactions of the recently discovered Higgs boson using matrix element techniques with the information from its decay to four leptons and from associated Higgs boson production with two quark jets in either vector ...

Angles on CP-violation in Higgs boson interactions

open access: yesPhysics Letters B, 2019
CP-violation in the Higgs sector remains a possible source of the baryon asymmetry of the universe. Recent differential measurements of signed angular distributions in Higgs boson production provide a general experimental probe of the CP structure of ...
