most research has been based on SWE [23]. In SWE, real-time rapid tissue deformation induced by an external compression device generates a shear wave that propagates perpendicularly to the main US beam [20,23,24]. The US scanner can monitor...
Most dark sector phenomenological studies, however, take the approach of 'switching on' only one individual portal at a time. In this article, we investigate a broader scenario of two simultaneous dark sector portals, namely, the neutrino and vector portals, and focus on one generic ...
