Belle II yields the first results: In search of the Z′ boson

The Belle II experiment has been collecting data from physical measurements for about one year. After several years of rebuilding work, both the SuperKEKB electron–positron accelerator and the Belle II detector have been ...

Engineers model mutations causing drug resistance

Whether it is a drug-resistant strain of bacteria, or cancer cells that no longer react to the drugs intended to kill them, diverse mutations make cells resistant to chemicals, and "second generation" approaches are needed. ...

States suspending standardized tests as schools close

Closing schools to combat the spread of the coronavirus is having a sweeping impact on an annual rite of spring: the standardized tests that are dreaded by millions of students and teachers alike.

New LHCb analysis still sees previous intriguing results

At a seminar today at CERN, the LHCb collaboration presented a new analysis of data from a specific transformation, or "decay," that a particle called B0 meson can undergo. The analysis is based on twice as many B0 decays ...

Machine-learning technology to track odd events among LHC data

Nowadays, artificial neural networks have an impact on many areas of our day-to-day lives. They are used for a wide variety of complex tasks, such as driving cars, performing speech recognition (for example, Siri, Cortana, ...

25 years on: A single top quark partners with the Z boson

A quarter-century after its discovery, physicists at the ATLAS Experiment at CERN are gaining new insight into the heaviest-known particle, the top quark. The huge amount of data collected during Run 2 of the LHC (2015-2018) ...

Exotic atomic nuclei reveal traces of new form of superfluidity

Recent observations of the internal structure of the rare isotope ruthenium-88 shed new light on the internal structure of atomic nuclei, a breakthrough that could also lead to further insights into how some chemical elements ...
