Author(s): M. Constantinou, M. Costa, R. Frezzotti, V. Lubicz, G. Martinelli, D. Meloni, H. Panagopoulos, and S. Simula (ETM Collaboration) We present the results of the first lattice QCD calculation of the K → π matrix elements of the chromomagnetic operator O CM = g s ¯ σ μ ν G μ ν d , which appears in the effective Hamiltonian describing Δ S = 1 transitions in and beyond the standard model. Having dimension five, the chromomagnetic operator is charact... [Phys. Rev. D 97, 074501] Published Mon Apr 02, 2018
