Neg 𝓵 sol exists iff

StandardModel.HiggsField.Potential.neg_𝓵_sol_exists_iff

Plain-language statement

For an element P of Potential with l < 0 and a real c : ℝ, there exists a Higgs field φ and a spacetime point x such that P.toFun φ x = c iff one of the following two conditions hold: - 0 < μ2 and c ≤ 0. That is, if l is negative and μ2 positive, then the potential takes every non-positive value. - or μ2 ≤ 0 and `c ≤ - μ2 ^ 2 / (4...
