Title: Light-emitting Top Quarks
Abstract: The LHC near Geneva, Switzerland, has been delivering an unprecedented amount of data, using the most energetic proton beams ever devised. A signature of new physics never before observed could well be hidden in the data that we have recorded using the CMS detector. In this talk, I will describe the most precise measurements of the properties of the top quark, which is the heaviest subatomic particle ever discovered. Top quarks are copiously produced at the LHC thus providing us with an ideal opportunity to use them as a tool to search for new physics. In particular, I will describe our latest result on the measurement of the rate of photons emitted from top quarks and summarize the main tt+X associate production. We are living in exciting times where new ideas about the universe can be tested in ways never before possible.
