Bounce Cosmology in a Locally Scale Invariant Physics with a U(1) Symmetry [PDF]
UniverseAn asymmetric non-singular bouncing cosmological model is proposed in the framework of a locally scale-invariant scalar-tensor version of the standard model of particle physics and gravitation. The scalar field ϕ is complex.

Model-Independent Searches for New Physics in Multi-Body Invariant Masses [PDF]
Universe, 2021 Model-independent searches for physics beyond the Standard Model typically focus on invariant masses of two objects (jets, leptons or photons). In this study, we explore opportunities for similar model-agnostic searches in multi-body invariant masses. In
