Symmetry between up and down quarks is more broken than expected
Surprising results from the NA61/SHINE collaboration at CERN show that this so-called isospin asymmetry could point to gaps in physicists’ understanding of how quarks and gluons combine
-
A new piece in the matter–antimatter puzzle
The LHCb experiment at CERN has revealed a fundamental asymmetry in the behaviour of particles called baryons
-
A bestiary of exotic hadrons
The LHC is engaged in a complex quest to understand the exotic offspring of one of the fundamental forces of nature
-
Observing triplets of weak bosons
ATLAS reports the first observation of a Z boson accompanied by two other carriers of the weak force

The other 99%
Near-miss collisions at the Large Hadron Collider are shedding light on the dynamics of gluons, which contribute 99% to the mass of protons and neutrons

Clocking nature’s heaviest elementary particle
The CMS collaboration has tested whether top quarks play by Einstein’s rules all day and all night

The measurement of a lifetime
New ATLAS measurement of the lifetime of the electrically neutral beauty meson is the most precise to date
-
LHCb sheds light on two pieces of the matter–antimatter puzzle
The collaboration has found evidence of CP violation in decays of baryons and in decays of beauty hadrons into charmonium particles
