A lower bound on the positive semidefinite rank of convex bodies
The positive semidefinite rank of a convex body $C$ is the size of its smallest positive semidefinite formulation. We show that the positive semidefinite rank of any convex body $C$ is at least $\sqrt{\log d}$ where $d$ is ... 
Relativistic magnetised perturbations: Magnetic pressure versus magnetic tension
(IoP, 20180516)We study the linear evolution of magnetised cosmological perturbations in the postrecombination epoch. Using full general relativity and adopting the ideal magnetohydrodynamic approximation, we refine and extend the ... 
Gauge Mediation in the NMSSM with a Light Singlet: Sparticles within the Reach of LHC Run II
Relatively light stops in gauge mediation models are usually made compatible with the Higgs mass of 125 GeV by introducing direct Higgsmessenger couplings. We show that such couplings are not necessary in a simple and ...
