Connecting Localization and Wall-Crossing via D-Branes
Chih-Kai Chang, Heng-Yu Chen, Dharmesh Jain +1
We demonstrate explicitly that the vacuum expectation values (vevs) of BPS line operators in 4d N=2 super Yang-Mills theory compactified on a circle, computed by localization techn…
A Model of Quark and Lepton Mixing and Mass Hierarchy
S. M. Barr, Heng-Yu Chen
It is shown that an idea proposed in 1996 that relates in a qualitatively correct way the inter-family mass hierarchies of the up quarks, down quarks, charged leptons, and neutrino…
On Higgs Branch Localization of Seiberg-Witten Theories on Ellipsoid
Heng-Yu Chen, Tsung-Hsuan Tsai
In this note, we consider so-called "Higgs Branch Localization" for four dimensional N=2 field theories on 4d ellipsoid. We find a new set of saddle point equations arising from ad…
A Single Source for All Flavor Violation
Stephen M. Barr, Heng-Yu Chen
In a model proposed in 2012, all flavor mixing has a single source and is governed by a single "master matrix." This model was shown to give several predictions for quark and lepto…
