Odd gluon compounds may be lurking in protons

February 9, 2018
Protons are known to contain quarks and gluons. But are gluons behaving as expected?Scientists from the TOTEM (Total, elastic and diffractive cross-section measurement) collaboration may have found indirect evidence of a subatomic gluon-compound in proton-proton collisions. First theorised in the 1970s, such a state, then dubbed “Odderon”, consists of an odd number of gluons.Usually, the protons t

First high-precision LHC measurement of W boson mass

February 12, 2018
In a paper published today in the European Physical Journal C, the ATLAS Collaboration reports the first high-precision measurement at the Large Hadron Collider (LHC) of the mass of the W boson. This is one of two elementary particles that mediate the weak interaction – one of the forces that govern the behaviour of matter in our universe. The reported result gives a value of 80370±19 MeV for the
