Explanation of nearby SNRs for primary electron excess and proton spectral bump

Physics Letters B, 2022
Several groups have reported a possible excess of primary electrons at high energies with the joint fit of the positron fraction and total electron/positron spectra.

Extending global fits of 4D Composite Higgs Models with partially composite leptons

Journal of High Energy Physics
We perform the first convergent Bayesian global fits of 4D Composite Higgs Models with partially-composite third generation quarks and leptons based on the minimal SO(5) → SO(4) symmetry breaking pattern.

Revisiting cosmological constraints on supersymmetric SuperWIMPs

European Physical Journal C: Particles and Fields
SuperWIMPs are extremely weakly interacting massive particles that inherit their relic abundance from late decays of frozen-out parent particles. Within supersymmetric models, gravitinos and axinos represent two of the most well motivated superWIMPs.

Primordial black holes from the ultraslow-roll phase in the inflaton–curvaton mixed field inflation

European Physical Journal C: Particles and Fields
Primordial black holes (PBHs) are a promising candidate for dark matter, as they can form in the very early universe without invoking new particle physics.

Searching accretion-enhanced dark matter annihilation signals in the Galactic Centre

Journal of High Energy Physics
This study reanalyzes the detection prospects of dark matter (DM) annihilation signals in the Galactic Center, focusing on velocity-dependent dynamics within a spike density near the supermassive black hole (Sgr A⋆).
