The Standard Theory of Particle Physics describes successfully the observed strong and electroweak interactions, but it is still unknown, how the masses of the leptons and quarks are generated. The observed flavor mixing of the quarks and leptons must be directly related to the mass generation. Presumably the flavor mixing angles are functions of the quark or lepton masses. The experimental data are in good agreement with the predictions of the "texture zero models". Of special interest is the physics of the neutrinos, in particular the large observed mixing angles and the very small masses of the neutrinos. These masses might be Majorana masses, implying that lepton number is not conserved. Thus the neutrino mass could be measured by the double beta decay experiments. At the Large Hadron Collider at CERN a new boson was discovered, which might be the "Higgs" boson. This boson might also be an excitation of the Z-boson, if the weak bosons are composite particles.
The International Conference on Massive Neutrinos will be held at the Nanyang Executive Centre from 9 to 13 February 2015 at NTU, Singapore.
