报告摘要:

The nature of neutrinos remains mysterious. If they are Majorana particles, there should be other lepton number violating effects besides their small mass. While the issue may be addressed at high energy colliders and in low energy precision experiments, the effective field theory approach offers a means to connect all experimental data at low and high energies to new physics underlying lepton number violation. In this talk, Ill take the example of lepton number violating kaon decay to illustrate how to accomplish this in the framework of effective field theory. Ill discuss several effective field theories defined by the electroweak scale and chiral symmetry breaking scale: how to build them correctly and how to link them all the way to new physics beyond the electroweak scale. Ill also emphasize that study of lepton number violating meson decays can provide information not available in the popular nuclear neutrinoless double beta decays.
