Distorted mass edges at LHC from supersymmetric leptoquarks

Understand

Supersymmetric (SUSY) grand unified theories based on exceptional gauge groups such as E6 have recently triggered a lot of interest.

• Aside from top-down motivations, they contain phenomenologically interesting states with leptoquark quantum numbers.
• Their SUSY partners, leptoquarkinos, will appear similar to all R-odd particles in decay cascades, but mass edges in kinematic distributions- originating from the same semiexclusive final states-will however have major differences to the corresponding edges of ordinary squarks.
• This distortion of standard observables bears the opportunity to detect them at the LHC, but may also pose significant confusion of underlying model assumptions, which should be handled with care and, if interpreted falsely, might even prevent a possible discovery.
