viscous electron fluids have emerged recently as a new paradigm of strongly-correlated electron transport in solids. here we report on a direct observation of the transition to this long-sought-for state of matter in a high-mobility electron system in graphene. unexpectedly, the electron flow is found to be interaction... | fluidity onset in graphene |
a search is presented for physics beyond the standard model (sm) using electron or muon pairs with high invariant mass. a data set of proton-proton collisions collected by the cms experiment at the lhc at $\sqrt{s} =$ 13 tev from 2016 to 2018 corresponding to a total integrated luminosity of up to 140 fb$^{-1}$ is anal... | search for resonant and nonresonant new phenomena in high-mass dilepton final states at $\\sqrt{s} = $ 13 tev |
at colliders, neutral long-lived particles can be detected through displaced decay products or as missing energy. which search strategy is better depends on the particle's decay length just as on the detector properties. we investigate the complementarity of displaced and invisible signatures for the belle ii experimen... | displaced or invisible? alps from b decays at belle ii |
the cross section for coherent elastic neutrino-nucleus scattering (ce ν ns ) depends on the response of the target nucleus to the external current, in the standard model (sm) mediated by the exchange of a z boson. this is typically subsumed into an object called the weak form factor of the nucleus. here, we provide re... | coherent elastic neutrino-nucleus scattering: eft analysis and nuclear responses |
we show that the rate for dark-matter-electron scattering in an arbitrary material is determined by an experimentally measurable quantity, the complex dielectric function, for any dark matter interaction that couples to electron density. this formulation automatically includes many-body effects, eliminates all systemat... | determining dark-matter-electron scattering rates from the dielectric function |
confirmation of accelerated expansion of the universe probed the concept of dark energy theory, and since then, numerous models have been introduced to explain its origin and nature. the present work is based on reconstructing dark energy by parametrization of the deceleration parameter in the flrw universe filled with... | constraints on the parameterized deceleration parameter in frw universe |
