Abstract:

Quirks are long-lived exotic particles that are charged under both the Standard Model (SM) gauge group and a new confining gauge group. The mass of the lightest quirk is much larger than the confinement scale (Λ) of the new gauge group. Due to the confining gauge force, two quirks will start to oscillate after production and leave a kinky trajectory insider tracker. In this paper, I will introduce how to discover the quirk pair production signals at the LHC by utilizing the ionization energy loss information inside tracker.
