The CMS experiment has conducted a search for heavy beyond-standard-model particles (referred to as a Z′ boson) that give rise to a top quark-antiquark pair decaying into hadrons. The search excludes the existence of the new Z′ boson with…
With the discovery of the Higgs boson in 2012, an important piece in our puzzle to understand the Universe was found. However, there are still many open questions: why is the Higgs boson so light? What is dark matter? How does gravity work at…
The discovery of the Higgs boson (H), particularly with its decay into two electroweak gauge bosons WW and ZZ, marked a milestone in particle physics. This groundbreaking discovery not only answered long-standing questions but also inspired new…
The Standard Model (SM) of particle physics has been a cornerstone of our understanding of the subatomic realm, providing precise predictions, many of which have been tested by the ATLAS and CMS experiments at the CERN LHC. However, despite…
