A Little Solution to the Little Hierarchy Problem: A Vector-like Generation
Peter W. Graham, Ahmed Ismail, Surjeet Rajendran +1
We present a simple solution to the little hierarchy problem in the MSSM: a vector-like fourth generation. With O(1) Yukawa couplings for the new quarks, the Higgs mass can natural…
A Domino Theory of Flavor
Peter W. Graham, Surjeet Rajendran
We argue that the fermion masses and mixings are organized in a specific pattern. The approximately equal hierarchies between successive generations, the sizes of the mixing angles…
Decaying Dark Matter as a Probe of Unification and TeV Spectroscopy
Asimina Arvanitaki, Savas Dimopoulos, Sergei Dubovsky +3
In supersymmetric unified theories the dark matter particle can decay, just like the proton, through grand unified interactions with a lifetime of order of 10^{26} sec. Its decay p…
