Abstract
One- and two-zero textures for the flavor neutrino mass matrix have been successful in explaining mixing in the neutrino sector. Conservatively, six cases of one-zero textures and seven cases of two-zero textures are compatible with observations. We show that one case may be the most natural in the one- and two-zero textures schemes if tiny neutrino masses are generated by the type-II seesaw mechanism in triplet Higgs models.

Summary
The origin of the tiny masses and flavor mixing of neutrinos is a long-term mystery in particle physics. The seesaw mechanism is one of the leading theoretical mechanisms for generating tiny neutrino masses. There are three types of seesaw mechanisms [1]
