Have you heard of vector-like quarks? They are hypothetical particles which would provide an explanation to the value of the Higgs boson mass, which is still a mystery. Vector-like quarks are predicted by a variety of theories beyond the Standard…

The processes that are mostly studied at the LHC are caused by energetic collisions where the protons break up into their constituents, the quarks and gluons, which recombine to form composite hadrons. However, many proton-proton interactions result…

“The important thing”, said Einstein, “is not to stop questioning”, and we, as humans, never have. What is it all made up of? How does it fit together? We’ve been yearning to answer these questions for aeons, with our collective efforts culminating…
