Abstract Searches for heavy neutrino emission in K + → e + ν e and K + → μ + ν µ decays have provided very powerful constraints on sterile neutrinos and their mixings. In this talk at Kaon-2022 we discuss theoretical aspects of these searches and remark on recent experimental progress.more » « less

Abstract We consider spin–spin correlation functions for spins along a row, R n = ⟨ σ 0,0 σ n ,0 ⟩, in the two-dimensional Ising model. We discuss a method for calculating general- n expressions for coefficients in high-temperature and low-temperature series expansions of R n and apply it to obtain such expressions for several higher-order coefficients. In addition to their intrinsic interest, these results could be useful in the continuing quest for a nonlinear ordinary differential equation whose solution would determine R n , analogous to the known nonlinear ordinary differential equation whose solution determines the diagonal correlation function ⟨ σ 0,0 σ n , n ⟩ in this model.more » « less
