String Consistency, Heavy Exotics, and the 750 GeV Diphoton Excess at the LHC: Addendum
Mirjam Cvetic, James Halverson, Paul Langacker
We study models with heavy exotics that account for the LHC GeV diphoton excess in light of current vector-like quark bounds. Utilizing only exotics that may appear in three-…
String Consistency, Heavy Exotics, and the GeV Diphoton Excess at the LHC
Mirjam Cvetič, James Halverson, Paul Langacker
String consistency conditions are stronger than anomaly cancellation and can require the addition of exotics in the visible sector. We study such exotics and demonstrate that they…
Stringy Hidden Valleys
Mirjam Cvetič, James Halverson, Hernan Piragua
We study gauge theories where quasi-hidden sectors are added to the MSSM for the sake of string consistency conditions which would otherwise not be satisfied. We focus on quiver ga…
Ultraviolet Completions of Axigluon Models and Their Phenomenological Consequences
Mirjam Cvetič, James Halverson, Paul Langacker
The CDF and D0 collaborations have observed a forward-backward asymmetry in t-tbar production at large invariant mass in excess of the standard model prediction. One explanation in…
Implications of String Constraints for Exotic Matter and Z' s Beyond the Standard Model
Mirjam Cvetič, James Halverson, Paul Langacker
Global consistency of string compactifications places constraints on the chiral matter spectrum of a gauge theory which include those necessary for the absence of cubic nonabelian…
Phenomenology of A Three-Family Standard-like String Model
Mirjam Cvetic, Paul Langacker, Gary Shiu
We discuss the phenomenology of a three-family supersymmetric Standard-like Model derived from the orientifold construction, in which the ordinary chiral states are localized at th…
