Aspirin versus Placebo in Pregnancies at High Risk for Preterm Preeclampsia

open access: yesNew England Journal of Medicine, 2017
Background Preterm preeclampsia is an important cause of maternal and perinatal death and complications. It is uncertain whether the intake of low‐dose aspirin during pregnancy reduces the risk of preterm preeclampsia. Methods In this multicenter, double‐

Light scalar dark matter at neutrino oscillation experiments

open access: yesJournal of High Energy Physics, 2018
Couplings between light scalar dark matter (DM) and neutrinos induce a perturbation to the neutrino mass matrix. If the DM oscillation period is smaller than ten minutes (or equivalently, the DM particle is heavier than 0.69×10−17 eV), the fast-averaging

On the quantisation of complex higher derivative theories and avoiding the Ostrogradsky ghost

open access: yesNuclear Physics B, 2017
Generic higher derivative theories are believed to be fundamentally unphysical because they contain Ostrogradsky ghosts. We show that within complex classical mechanics it is possible to construct higher derivative theories that circumvent the ...

Vlasov description of the effects of nonlinear chromaticity on transverse coherent beam instabilities

open access: yesPhysical Review Accelerators and Beams, 2018
This paper extends the existing Vlasov theory for transverse coherent beam instabilities to account for nonlinear chromaticity. It confirms the hypothesis that nonlinear chromaticity has two effects on the beam dynamics: (i) it changes the effective ...

The light radion window

open access: yesJournal of High Energy Physics, 2018
Inspired by the Contino-Pomarol-Rattazzi mechanism we explore scenarios with a very light (1 keV to 10 GeV) radion which could be associated with the suppression of the electroweak contribution to vacuum energy.
