Coherence from interference: a solvable model of sub-GeV dark matter-nucleus scattering
Journal of High Energy PhysicsHow do dark matter-nucleus interactions transition from the regimes of coherent scattering, where single phonons are produced, to that of individual nuclear recoils? Answering this question relies on understanding multiphonon excitations.

Search for Milli-Charged particles from the Sun at IceCube
Journal of High Energy Physics, 2022 It is assumed that heavy dark matter particles ϕ with O(TeV) mass captured by the Sun may decay to relativistic light milli-charged particles (MCPs). These MCPs could be measured by the IceCube detector.

Mutant p53R273H disrupts PDPK1 homodimerization and contributes to PDPK1 activation
Molecular Oncology, EarlyView.How mutant p53R273H drives AKT signaling is unclear. We show that p53R273H, but not wild‐type, directly binds PDPK1 via a mutation‐dependent conformational change. This interaction disrupts inhibitory PDPK1 homodimerization and enhances AKT phosphorylation.

Z ′ portal dark matter with observable ∆N eff
Journal of High Energy PhysicsIn the conventional Z ′ portal dark matter scenario, the prediction of detectable dark matter χ typically relies on the collider sensitivities of Z ′ and direct detection, where the Majorana type right-handed neutrinos are usually assumed.

FEBS Open Bio, EarlyView.Repair of neuronal DNA damage in Alzheimer's disease by KCL‐286. (A) Amyloid‐β oligomers and plaques impair neuronal DNA repair pathways, leading to DNA double‐strand breaks and glial activation. (B) KCL‐286 activates RARβ/RXR signalling via retinoic acid response elements (RAREs), associated with increased BRCA1 expression, enhanced DNA repair and ...

Gamma-ray signatures of thermal misalignment dark matter
Journal of High Energy PhysicsThermal misalignment is a viable dark matter scenario where the misalignment of a dark matter scalar, feebly coupled to the Standard Model particles, is generated through thermal effects from the primordial plasma.

Advanced Engineering Materials, EarlyView.Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.

A radiative neutrino mass model with semi-annihilating boosted dark matter
Journal of High Energy PhysicsBoosted dark matter can provide a distinctive signature of a non-minimal dark sector. In this work, we construct a radiative neutrino mass model that allows for the production of boosted dark matter in the present universe through semi-annihilation.

Multilepton signatures from dark matter at the LHC
Journal of High Energy Physics, 2022 Leptonic signatures of Dark Matter (DM) are one of the cleanest ways to discover such a secluded form of matter at high energy colliders. We explore the full parameter space relevant to multi-lepton (2- and 3-lepton) signatures at the Large Hadron ...

Probing the Fundamental Nature of Particle Dark Matter
Understanding the fundamental nature of dark matter (DM) is one of the most significant scientific challenges of our time. A compelling hypothesis is that DM consists of a new, yet-to-be-discovered particle. Among the leading candidates are weakly interacting massive particles (WIMPs) and axion-like particles (ALPs), both of which can be investigated ...
