Higgs bosons can decay in multiple ways; in one scenario, a Higgs transforms into a top quark or a W boson, either of which would in turn immediately break up into two long-lived, detectable photons.
Research objectives and contents The project is to measure the mass of the W boson, the charged mediator of the weak force, and to study its couplings.
Washington, Mar 3 ( ANI ): Physicists including one of Indian origin have determined the world's most precise measurement of the mass of the W boson, which is one of nature's elementary particles.
Through detailed and persistent explanations, the authors track the development in this field from the first theoretical proposal of the W boson to today's consistent and repeatable mathematical applications.
Although the W boson was already known to physicists, identifying known particles is vital for calibration of the detectors like Atlas.
As an example, Turner points out the accepted theoretical claim that elementary particles known as the W boson and the Z boson had no mass when the universe first exploded into being.
The lower-energy boundary was established by the Large Electron-Positron (LEP) collider at CERN in the 1990s, whereas the upper boundary is a softer limit established by indirect evidence, such as the masses of the top quark and the W boson.
