The paper discusses the viability of Higgs Inflation in light of the BICEP2 collaboration's detection of B-modes in the cosmic microwave background radiation. The authors argue that Higgs Inflation is unlikely to accommodate the new measurement unless extreme fine-tuning or new beyond-standard-model fields are considered. They explore the gauge dependence of the effective potential and conclude that it does not resolve the incompatibility between the BICEP2 observation and Higgs Inflation predictions.
