EDITORS' SUGGESTION

Search for Invisible Decays of a Higgs Boson Produced in Association with a $Z$ Boson in ATLAS

G. Aad et al. (ATLAS Collaboration)

Phys. Rev. Lett. 112, 201802 (2014) - Published 20 May, 2014

The decay of the Higgs boson into “invisible particles” delivers no evidence of physics beyond the standard model, putting new limits on dark matter theories.

Cell Size Regulation in Bacteria

Ariel Amir

Phys. Rev. Lett. 112, 208102 (2014) - Published 23 May, 2014

EDITORS' SUGGESTION

Electroweak Vacuum Stability in Light of BICEP2

Malcolm Fairbairn and Robert Hogan

Phys. Rev. Lett. 112, 201801 (2014) - Published 20 May, 2014

The large tensor modes seen by BICEP2 suggest that fluctuations during inflation will destabilize the electroweak vacuum.

EDITORS' SUGGESTION

Jan Wiersig

Phys. Rev. Lett. 112, 203901 (2014) - Published 20 May, 2014

So-called exceptional points, degenerate quantum states, allow higher energy splitting under the same perturbation conditions, greatly improving the detection sensitivity of sensors.
