Unitarity and Monojet Bounds on Models for DAMA, CoGeNT, and CRESST-II
Ian M. Shoemaker, Luca Vecchi
If dark matter interacts with quarks or gluons, the mediator of these interactions is either directly accessible at the LHC or is so heavy that its effects are encoded in contact o…
Probing Nonstandard Standard Model Backgrounds with LHC Monojets
Alexander Friedland, Michael L. Graesser, Ian M. Shoemaker +1
Monojet events at colliders have been used to probe models of dark matter and extra dimensions. We point out that these events also probe extensions of the Standard Model modifying…
A dark force for baryons
Michael L. Graesser, Ian M. Shoemaker, Luca Vecchi
We suggest the existence of a fundamental connection between baryonic and dark matter. This is motivated by both the stability of these two types of matter as well as the observed…
Color & Weak triplet scalars, the dimuon asymmetry in decay, the top forward-backward asymmetry, and the CDF dijet excess
Luca Vecchi
The new physics required to explain the anomalies recently reported by the D0 and CDF collaborations, namely the top forward-backward asymmetry (FBA), the like-sign dimuon charge a…
Fermions and Goldstone bosons in an asymptotically safe model
F. Bazzocchi, M. Fabbrichesi, R. Percacci +2
We consider a model in which Goldstone bosons, described by a SU(N) chiral nonlinear sigma model, are coupled to an N-plet of colored fermions by means of a Yukawa interaction. We…
Asymmetric WIMP dark matter
Michael L. Graesser, Ian M. Shoemaker, Luca Vecchi
In existing dark matter models with global symmetries the relic abundance of dark matter is either equal to that of anti-dark matter (thermal WIMP), or vastly larger, with essentia…
