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 ...

Relational Supersymmetry via the Dressing Field Method and Matter‐Interaction Supergeometric Framework

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 ...

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

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

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.

Foundations of Ghost Stability

Fortschritte der Physik, Volume 73, Issue 4, April 2025.
Abstract The authors present a new method to analytically prove global stability in ghost‐ridden dynamical systems. The proposal encompasses all prior results and consequentially extends them. In particular, it is shown that stability can follow from a conserved quantity that is unbounded from below, contrary to expectation.

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 ...

Multi-scalar signature of self-interacting dark matter in the NMSSM and beyond

Journal of High Energy Physics, 2021
This work studies the self-interacting dark matter (SIDM) scenario in the general NMSSM and beyond, where the dark matter is a Majorana fermion and the force mediator is a scalar boson.

Notes on Characterizations of 2d Rational SCFTs: Algebraicity, Mirror Symmetry, and Complex Multiplication

Fortschritte der Physik, Volume 73, Issue 1-2, February 2025.
Abstract S. Gukov and C. Vafa proposed a characterization of rational N=(1,1)$N=(1,1)$ superconformal field theories (SCFTs) in 1+1$1+1$ dimensions with Ricci‐flat Kähler target spaces in terms of the Hodge structure of the target space, extending an earlier observation by G. Moore.
