Repurposing lattice QCD results for composite phenomenology
Thomas DeGrand, Ethan T. Neil
A number of proposed extensions of the Standard Model include new strongly interacting dynamics, in the form of SU(N) gauge fields coupled to various numbers of fermions. Often, th…

Mapping and Probing Froggatt-Nielsen Solutions to the Quark Flavor Puzzle
Claudia Cornella, David Curtin, Ethan T. Neil +1
The Froggatt-Nielsen (FN) mechanism is an elegant solution to the flavor problem. In its minimal application to the quark sector, the different quark types and generations have dif…
