A subatomic particle called the W boson may be heavier than expected, a surprising finding that might lead to a shake-up of physics' grand model of how the world works on the microscale. When you ...

After a decade-long analysis, a collaboration of physicists has made the most precise measurement of the mass of a key particle – and it may unravel physics as we know it. The new measurement differs ...

Living on: data taken by the now defunct CDF experiment has revealed a surprising mass for the W boson. (Courtesy: Fermilab) The most precise measurement to date of the mass of the W boson has yielded ...

A new measurement of a fundamental particle called the W boson appears to defy the standard model of particle physics, our current understanding of how the basic building blocks of the universe ...

A ground state atomic nucleus can be something of a black box, masking subtle details about its structure behind the aggregate interplay of its protons and neutrons. This is one reason nuclear ...

Physicists have found that an elementary particle called the W boson appears to be 0.1 percent too heavy—a tiny discrepancy that could foreshadow a huge shift in fundamental physics. The measurement, ...

There’s something amiss with a mass. A new measurement of the mass of an elementary particle, the W boson, has defied expectations. The result hints at a possible flaw in physicists’ otherwise ...

It’s often said in science that extraordinary claims require extraordinary evidence. Recent measurements of the mass of the elementary particle known as the W boson provide a useful case study as to ...

While this may complicate the quest for a clear experimental signature of quantum gravity, it does not render such tests useless. According to the research team, both classical and quantum models of ...

In nuclear physics, "magic numbers" identify specific numbers of protons or neutrons that lead to especially stable nuclei. Recognizing these numbers helps scientists better understand the structure ...

As the collapsed core of a massive star, a neutron star is a small but incredibly dense object, packing up to three times the ...

The weak gravitational pull on a particle just half the mass of a grain of sand has been measured for the first time. This most precise measurement of its kind is a breakthrough towards the quantum ...
