Journal of High Energy Physics, 2017 The LUX experiment has recently set very strong constraints on spin-independent interactions of WIMP with nuclei. These null results can be accommodated in NMSSM provided that the effective spin-independent coupling of the LSP to nucleons is suppressed ...

Singularity variables for missing energy event kinematics
Journal of High Energy Physics, 2020 We discuss singularity variables which are properly suited for analyzing the kinematics of events with missing transverse energy at the LHC. We consider six of the simplest event topologies encountered in studies of leptonic W -bosons and top quarks, as ...

Dark sectors and enhanced h → τ μ transitions
Journal of High Energy Physics, 2017 LHC searches with τ leptons in the final state are always inclusive in missing-energy sources. A signal in the flavor-violating Higgs decay search, h → τ μ, could therefore equally well be due to a flavor conserving decay, but with an extended decay ...

Neutrino Magnetic Moment in the Doublet‐Singlet Leptoquark Model
Advances 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 ...

Natural emergence of neutrino masses and dark matter from R-symmetry
Journal of High Energy Physics, 2017 We propose a supersymmetric extension of the Standard Model (SM) with a continuous global U(1) R symmetry. The R-charges of the SM fields are identified with that of their lepton numbers. As a result, both bilinear and trilinear ‘R-parity violating’ (RPV)

Thermal relic of self-interacting dark matter with retarded decay of mediator
Journal of High Energy Physics, 2021 The existence of a light mediator is beneficial to some phenomena in astroparticle physics, such as the core-cusp problem and diversity problem. It can decouple from Standard Model to avoid direct detection constraints, generally realized by retard decay

Annalen der Physik, Volume 537, Issue 9, September 2025.Applications of the Dressing Field Method are reviewed and further expanded to the very foundations of the supersymmetric framework, where it allows to build relational supersymmetric field theory. Furthermore, a novel approach is proposed giving a unified description of fermionic matter fields and bosonic gauge fields: a Matter‐Interaction ...

Zero-range effective field theory for resonant wino dark matter. Part I. Framework
Journal of High Energy Physics, 2017 The most dramatic “Sommerfeld enhancements” of neutral-wino-pair annihilation occur when the wino mass is near a critical value where there is a zero-energy S-wave resonance at the neutral-wino-pair threshold.

Dark Dimension With (Little) Strings Attached
Fortschritte der Physik, Volume 73, Issue 4, April 2025.Abstract A relation between dark energy and the scale of new physics in weakly coupled string theory is motivated. This mixing between infrared and ultraviolet physics leads to a unique corner for real‐world phenomenology: barring fine‐tunings, the authors are naturally led to the “dark dimension” scenario, a single mesoscopic extra dimension of micron

The motivation and status of two-body resonance decays after the LHC Run 2 and beyond
Journal of High Energy Physics, 2020 Searching for two-body resonance decays is a central component of the high energy physics energy frontier research program. While many of the possibilities are covered when the two bodies are Standard Model (SM) particles, there are still significant ...
