Unparticle physics at hadron collider via dilepton production

Understand

The scale invariant unparticle physics recently proposed by Georgi could manifest at low energies as non integral number d_U of invisible particles.

• Unparticles if existing, could couple to the Standard Model fields and consequently affect the collider phenomenology.
• We consider the DY process to explore effects of the peculiar propagator of the scalar and tensor unparticle operators.
• To probe these effects at hadron collider one needs to go beyond LO in QCD and hence the quantitative impact of QCD corrections for unparticle physics at LHC is investigated.
