Deep Inelastic Scattering 2017 (DIS17) demonstrates how deep inelastic scattering (DIS) and related topics permeate most aspects of high-energy physics
Read article 'Precision study reveals proton to be lighter'
A team in Germany has made the most precise measurement to date of the mass of a single proton, achieving a precision of 32 parts-per-trillion (ppt). The result not only improves on the precision of ...
Read article 'KEDR pins down R at low energies'
The KEDR collaboration has used the VEPP-4M electron–positron collider at the Budker Institute in Russia to make the most precise measurement of the quantity “R” in the low-energy range. R is de...
Read article 'Lead nuclei under scrutiny at LHCb'
In 2016 the LHC collided protons and lead nuclei for the first time at a centre-of-mass energy of 8.16 TeV per nucleon–nucleon pair. In lead–lead collisions, the formation of the quark–gluon p...
Read article 'J/ψ mesons reveal stronger nuclear effects in pPb collisions'
Quarkonium states, such as the J/ψ meson, are prominent probes of the quark–gluon plasma (QGP) formed in high-energy nucleus–nucleus (AA) collisions. That bulk J/ψ production is suppressed in AA...
Read article 'ALICE zooms in on evolution of the quark–gluon plasma'
The precise particle-identification and momentum-measurement capabilities of the ALICE experiment allow researchers to reconstruct a variety of short-lived particles or resonances in heavy-ion collisi...
