Can we read the universe’s book of secrets?

The Standard Model of particle physics, despite accurately describing the building-blocks of matter and their interactions, leaves some important questions unanswered. To address those, theories proposing hypothetical particles are developed. FASER, a small experiment at the CERN LHC, will search for some of them. To enhance its discovery potential, an instrument using novel high-resolution silicon sensors was just approved to be added to the experiment.
