Reaching a precision milestone

Our group member Vasily Sotnikov speaks about theoretical particle physics in general and his latest research results in particular.

He tells us about the newest precision milestone he and his collaborators reached for an important process at hadron colliders - this is the process when two protons collide and produce three highly energetical photons. Find out more about it, and learn how important it is to dive deep into mathematics and why a smoking gun signature makes calculations exciting.
