Read article 'Rare hyperon-decay anomaly under the spotlight'
The LHCb collaboration has shed light on a long-standing anomaly in the very rare hyperon decay Σ+ → pµ+µ– first observed in 2005 by Fermilab’s HyperCP experiment. The HyperCP team found ...

A new national facility at La Silla Observatory in Chile, operated by the European Southern Observatory (ESO), made its first observations at the beginning of the year.
Read article 'ATLAS measures rare top plus boson production'
In two new results, ATLAS presents strong evidence for the production of a single top quark in association with a Z boson.
Read article 'CMS hunts for heavy neutral leptons'
Through their mixing with the Standard Model neutrinos, sterile Majorana neutrinos could be produced at the LHC in leptonic W-boson decays.

These two results suggest that charmed baryon formation might not be universal, and that the baryon/meson ratio depends on the collision system.

That is half the energy set out five years ago in the ILC’s technical design report (TDR), shortening the length of the previous design (31 km) by around a third and slashing its cost by up to 40%.
