A fraction of the dark matter may consist a particle species that interacts much more strongly with Standard Model than typical weakly interacting massive (WIMP) similar mass. Such component could have avoided detection in searches for WIMP-like through its interactions material atmosphere and Earth slow it down significantly before reaching detectors underground. These same can also enhance density near Earth's surface to well above local galactic density. In this work, we propose two new...
We investigate the hypothesis that sexaquarks, hypothetical stable six-quark states, could be a significant component of dark matter. expand on previous studies sexaquark cosmology, accounting for possibility some relevant interaction cross sections might strongly suppressed below expectations based dimensional analysis. update direct-detection constraints sexaquarks comprising subdominant fraction matter, as well limits annihilation an antisexaquark from Super-Kamiokande. argue scenario...
Electronic materials can sustain a variety of unusual, but symmetry protected touchings valence and conduction bands, each which is identified by distinct topological invariant. Well-known examples include linearly dispersing pseudo-relativistic fermions in monolayer graphene, Weyl nodal-loop semimetals, biquadratic (bicubic) band touching bilayer (trilayer) as well mixed dispersions multi-Weyl systems. Here we show that depending on the underlying curvature, shear viscosity collisionless...
Abstract The search for a dark photon holds considerable interest in the physics community. Such force carrier would begin to illuminate sector. Many experiments have searched such particle, but so far it has proven elusive. In recent years concept of low mass gained popularity Of particular is 8 Be and 4 He anomaly, which could be explained by new fifth with 17 MeV/ c 2 . proposed Darklight experiment this potential at ARIEL 10-20 e + − invariant range. This proceeding will focus on...

We point out that dark matter can illuminate planetary skies via ultraviolet airglow. Dark annihilation products excite molecular hydrogen, which then deexcites to produce emission in the Lyman and Werner bands. search for this new effect by analyzing nightside radiation data from Voyager 1, 2, New Horizons flybys of Neptune, Uranus, Saturn, Jupiter. Our findings set constraints on matter-nucleon scattering cross section down about $10^{-40}~$cm$^2$. highlight future airglow measurements...
