Exotic Higgs Decays at a Muon Collider
JiJi Fan, Lingfeng Li, Tao Liu +2
We study the sensitivity of a future muon collider to exotic Higgs decays in a minimal scenario of Standard Model (SM) augmented with a light singlet scalar . We consider the de…

Pulse and Polarization Structures in Axion-Converted X-rays from Pulsars
JiJi Fan, Lingfeng Li, Chen Sun
Neutron stars (NS's) with their strong magnetic fields and hot dense cores could be powerful probes of axions, a classic benchmark of feebly-coupled new particles, through abundant…

The Juno Mission as a Probe of Long-Range New Physics
Praniti Singh, Shi Yan, Itamar J. Allali +2
Orbits of celestial objects, especially the geocentric and heliocentric ones, have been well explored to constrain new long-range forces beyond the Standard Model (SM), often refer…
