Bottomonium suppression in lead–lead collisions
The quarkonium yield is suppressed in heavy-ion collisions when compared with proton–proton collisions because the binding force is screened by the hot and dense medium.
A foremost accelerator physicist: Yong Ho Chin 1958–2019
A leading theoretical accelerator physicist and chair of the beam dynamics panel of the International Committee for Future Accelerators.
First light for supersymmetry
Ideas from supersymmetry have been used to address a longstanding challenge in optics – how to suppress unwanted spatial modes that limit the beam quality of high-power lasers.
MINOS squeezes sterile neutrino’s hiding ground
LSND, MiniBooNE and the reactor data are fairly compatible when interpreted in terms of sterile neutrinos, but they are in stark conflict with the null results from MINOS+ and IceCube.
CMS beam pipe to be mined for monopoles
A 6 m-long section will be cut into pieces and fed into a SQUID in the name of fundamental research.
Report reveals full reach of LHC programme
The High-Luminosity LHC, scheduled to operate from 2026, will increase the instantaneous luminosity of the LHC by at least a factor of five beyond its initial design luminosity.
Mysterious burst confounds astrophysicists
Hypotheses are that the Cow was either a compact object being destroyed when coming too close to a black hole, or a special type of supernova in which a black hole or magnetar is produced.
Probing gauge-boson polarisation
WZ production, with its clean experimental signature, offers a sensitive way to search for anomalies.
Charm mixing tests the Standard Model
Given LHCb’s current level of experimental precision, any sign of CP violation would be a clear indication of physics beyond the Standard Model.
CASTOR calorimetry delves into gluon saturation
This largely unexplored phenomenon is expected to occur when the gluons in a hadron overlap transversally, and is enhanced for hadrons with high atomic numbers.
