Read article 'LS1: on the home straight'
When the shift crew in the CERN Control Centre extracted the beams from the LHC on 14 February last year, it marked the beginning of the first long shutdown, LS1, not only for the LHC but for all of ...
Read article 'Tevatron experiments find missing piece in top-quark puzzle'
Data from the CDF and D0 experiments at the Tevatron have revealed one of the rarest methods of producing a top quark
Read article 'CDMS puts new constraints on dark-matter particles'
While it is now generally accepted that dark matter makes up the majority of the mass in the universe, little is known about what it is.
Read article 'Beauty-quark decays reveal photon polarization'
The Standard Model predicts that the photons emitted in b → sγ transitions, which can only occur through loop-level processes, are predominantly left-handed.
Read article 'First observation of Z-boson production via weak-boson fusion'
The fusion of two weak bosons is an important process that can be used to probe the electroweak sector of the Standard Model.
Read article 'Heavy stable charged particles: an exotic window to new physics'
As the LHC experiments improve the precision of their measurements of Standard Model processes, the extent of possibilities for new physics open to exploration is becoming ever more apparent.
Read article 'New results mark progress towards polarized ion beams in laser-induced acceleration'
The field of laser-induced relativistic plasmas and, in particular, laser-driven particle acceleration, has undergone impressive progress in recent years.
Read article 'NOvA experiment sees its first long-distance neutrinos'
On 11 February, the NOvA collaboration announced the detection of the first neutrinos in the long-baseline experiment’s far detector in northern Minnesota.
Read article 'New precision reached on electron mass'
Knowledge of the electron mass has been improved by a factor of 13, thanks to a clever extension of previous Penning-trap experiments.
Read article 'Fermi gamma-rays match dark-matter signal'
A new analysis of observations of the galactic centre by the Fermi Gamma-ray Space Telescope strengthens the case for a signal from annihilating dark matter. The authors claim that the excess emission...
