Unified framework links CP-violating Higgs parametrisations
—
What the study found The study provides a unified framework for relating different ways of describing CP-violating Higgs boson interactions. It also constructs explicit dictionaries to translate between commonly used parametrisations. Why the authors say this matters The authors say this matters because differing conventions and assumptions across the literature make translation between parametrisations nontrivial…
Mean-field approaches qualitatively capture heavy-quark QCD phase behavior
What the study found The study finds that three mean-field approximations applied to effective Polyakov loop theories can qualitatively determine the phase diagram of lattice QCD with heavy quarks using fully analytical methods. It also reports a first-order nuclear liquid-gas transition with a critical end point at very low temperatures and moderately heavy quarks. Why…
