Measuring the velocity and mass of stable massive particles using the ATLAS detector at the LHC

Show other versions (2)

A generic search for new detector-stable high-mass particles at the LHC using the ATLAS detector is conducted, by measuring the velocity of candidate tracks in ATLAS’ Inner Detector. Four novel new velocity estimation techniques are developed, the best of which achieve velocity resolutions of better...
