Beschreibung
We will discuss the use of recoil-free jet observables to systematically benchmark jet modification studies with precision and sensitivity, starting from the hardest components of jets. Here we focus on the recoil-free jet axis in defining di-jet and photon-jet angular decorrelation. This observable is not affected by the huge underlying event background and can be calculated and measured precisely. Also, since the recoil-free axis follow the dominant energy flow within jet, it is sensitive to any partonic energy loss mechanism which can deflect the axis direction. We will present Monte Carlos studies based on simulations with different jet quenching models. Future measurements of this observable will allow us to test the onset of jet quenching in the whole jet evolution history. This paves a path towards precision heavy ion jet modification studies using recoil-free observables.
