Soft-Dimuon Signature from Two-Component Scalar Dark Matter at the LHC
Alexander Belyaev, Manimala Chakraborti, Shu Chen +4
We explore the potential of the Large Hadron Collider to probe a two-component scalar dark matter scenario in the opposite-sign dimuon plus missing transverse energy final state, a…
Particle Cosmology
Venus Keus
Particle cosmology is the branch of science that seeks to understand the birth and evolution of the Universe by applying the principles of particle physics. It brings together the…
Chaotic Inflation RIDES Again
Venus Keus, Stephen F. King
Following the recent Atacama Cosmology Telescope (ACT) results, we revisit chaotic inflation based on a single complex scalar field with mass term , which usually predic…
Electroweak phase transition enhanced by a CP-violating dark sector
Venus Keus, Lucy Lewitt, Jasmine Thomson-Cooke
Within a well-motivated 3-Higgs doublet model, in which the extended dark sector accommodates CP violation, we analyse the electroweak phase transition (EWPT) at one- and two-loop…
Reinterpretation and preservation of data and analyses in HEP
Jon Butterworth, Sabine Kraml, Harrison Prosper +145
Data from particle physics experiments are unique and are often the result of a very large investment of resources. Given the potential scientific impact of these data, which goes…
Baryogenesis from Primordial CP Violation
Venus Keus, Edward W. Kolb
We present a novel Baryogenesis mechanism in which an asymmetry of scalars in a three-Higgs doublet model produced exiting a CP-violating inflationary set-up is translated into an…
