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 ...

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 ...

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 ...

The W boson particle was discovered in 1983. It is not just a fundamental particle in physics, but together with the Z boson, W boson is responsible for what is known as the weak force, which is one ...

Neutrino mass measurement techniques represent a cornerstone of modern particle physics and cosmology. Given the elusive nature of neutrinos, experimental approaches have evolved to measure their ...

The most precise measurement to date of the proton-electron mass ratio suggests that the proton may be lighter than previously thought. The result, from researchers in the Netherlands and France, ...

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

A recent study published in Nature combines data from two major experiments - NOvA in the United States and T2K in Japan - to observe with unprecedented precision how neutrinos, particles capable ...

In a milestone that could impact the future of physics, researchers have managed to place an upper mass limit on the subatomic particle called the neutrino. Without knowledge of the mass possessed by ...

Pasco Scientific is introducing a new Smart Cart, a low-friction cart with sensors that will allow students to collect data from experiments to learn physics concepts. With the use of the sensors, ...
