Dark Energy and Neutrino Flavor from the Weak Axion
Pedro Bittar, Carlos E. M. Wagner
Dynamical dark energy offers an alternative to a cosmological constant with distinct observational signatures. However, the small energy density scale, Hubble-sized mass, and Planc…

R-parity violation and 8 TeV four-jet events at the LHC
Pedro Bittar, Subhojit Roy, Carlos E. M. Wagner
The CMS Collaboration at the Large Hadron Collider (LHC) has observed two four-jet events with a total invariant mass of about 8 TeV; within each event, the jets can be paired into…

Self Consistent Thermal Resummation: A Case Study of the Phase Transition in 2HDM
Pedro Bittar, Subhojit Roy, Carlos E. M. Wagner
An accurate description of the scalar potential at finite temperature is crucial for studying cosmological first-order phase transitions (FOPT) in the early Universe. At finite tem…
