Neutrino Magnetic Moment in the Doublet‐Singlet Leptoquark Model

open access: yesAdvances in High Energy Physics, Volume 2026, Issue 1, 2026.
The transition magnetic moment for Majorana neutrinos is studied in a simple extension of the Standard Model. This extension incorporates two scalar Leptoquarks S1 and R~2 with quantum numbers 3¯,113,/ and (3, 2, 1/6), respectively. It is found that these Leptoquarks generate a sizable transition magnetic moment, particularly when the quark bottom is ...

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

A Superalgebra Within: Representations of Lightest Standard Model Particles Form a Z25$\mathbb {Z}_2^5$‐Graded Algebra

open access: yesAnnalen der Physik, Volume 537, Issue 12, December 2025.
 A set of particle representations, familiar from the Standard Model, collectively form a superalgebra. Those representations mirroring the behaviour of the Standard Model's gauge bosons, and three generations of fermions, are each included in this algebra, with exception only to those representations involving the top quark.

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.

Active Learning in Physics: From 101, to Progress, and Perspective

open access: yesAdvanced Quantum Technologies, Volume 8, Issue 12, December 2025.
In this review, the concept of active learning is introduced to the physicists at the level of beginner without requirement on background in machine learning. It includes most of the latest applications of active learning in branches of physics, covering but not being limited to quantum information, high energy physics, and condensed matter physics. It

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 ...

Single charged Higgs boson production at next generation linear colliders [PDF]

open access: yes, 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 ...

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.

Higher order and CP-violating effects in the neutralino and Higgs boson sectors of the MSSM [PDF]

open access: yes, 2010
Complete one-loop results are presented for neutralino and Higgs decay processes of the form chi^0_i->chi^0_j h_a and h_a->chi^0_i chi^0_j in the MSSM with CP-violating parameters.
