WebHiggs decays. Additional decay modes can thus be excluded with an upper limit that depends on the sample size. Figure 1: Expected contributions per class from each of the … Particle physicists study matter made from fundamental particles whose interactions are mediated by exchange particles – gauge bosons – acting as force carriers. At the beginning of the 1960s a number of these particles had been discovered or proposed, along with theories suggesting how they relate to each other, some of which had already been reformulated as field theories in which t…
