Mixed Sneutrinos, Dark Matter and the LHC
Zoe Thomas, David Tucker-Smith, Neal Weiner
We study the phenomenology of supersymmetric models in which gauge-singlet scalars mix with the MSSM sneutrinos through weak-scale terms. After reviewing the constraints on mix…
Mass Screening in Modified Gravity
Gregory Gabadadze, Alberto Iglesias
Models of modified gravity introduce extra degrees of freedom, which for consistency with the data, should be suppressed at observable scales. In the models that share properties o…
Faster polynomial multiplication via multipoint Kronecker substitution
David Harvey
We give several new algorithms for dense polynomial multiplication based on the Kronecker substitution method. For moderately sized input polynomials, the new algorithms improve on…
Why many theories of shock waves are necessary. Kinetic functions, equivalent equations, and fourth-order models
Philippe G. LeFloch, Majid Mohammadian
We consider several systems of nonlinear hyperbolic conservation laws describing the dynamics of nonlinear waves in presence of phase transition phenomena. These models admit under…
Strong CP Problem with 10^{32} Standard Model Copies
Gia Dvali, Glennys R. Farrar
We show that a recently proposed solution to the Hierarchy Problem simultaneously solves the Strong CP Problem, without requiring an axion or any further new physics. Consistency o…
Spectral Flow in AdS(3)/CFT(2)
Gaston Giribet, Ari Pakman, Leonardo Rastelli
We study the spectral flowed sectors of the H3 WZW model in the context of the holographic duality between type IIB string theory in AdS(3)x S^3 x T^4 with NSNS flux and the symmet…
