Physicists use machine learning techniques to search for exotic-looking collisions that could indicate new physics

Posted by in categories: particle physics, robotics/AI

One of the main goals of the LHC experiments is to look for signs of new particles, which could explain many of the unsolved mysteries in physics. Often, searches for new physics are designed to look for one specific type of new particle at a time, using theoretical predictions as a guide. But what about searching for unpredicted—and unexpected—new particles?
