Parameterizations of the Hubble Constant: Logarithmic vs Power-Law Expansion from the Binned Master Sample of SNe Ia
Maria Giovanna Dainotti, Avik Banerjee, Andre' LeClair +1
In view of the current and increasing evidence of a running Hubble constant, we investigate its redshift dependence within the flat CDM framework using a 20-bin analysis of the…

Non-perturbative renormalization group for pseudo-hermitian scalar fields in 4D
André LeClair
We define a model of 2 coupled SU(2) doublets of scalar fields in spacetime dimensions which have a rich structure of renormalization group (RG) flows to 1-loop when the SU(2)…

A rich structure of renormalization group flows for Higgs-like models in 4 dimensions
André LeClair
We consider coupled Higgs doublets which transform in the usual way under SU(2). By constructing marginal operators which satisfy an operator product expansion based on the SU(…
