Discriminating between technicolor and warped extra dimensional model via pp $\to$ ZZ channel

Understand

We explore the possibility to discriminate between certain strongly-coupled technicolor (TC) models and warped extra-dimensional models where the Standard Model fields are propagating in the extra dimension.

• We consider a generic QCD-like TC model with running coupling as well as two TC models with walking dynamics.
• We argue that due to the different production mechanisms for the lowest-lying composite tensor state in these TC theories compared to the first Kaluza-Klein graviton mode of warped extra-dimensional case, it is possible to distinguish between these models based on the angular analysis of the reconstructed longitudinal Z bosons in the $pp \to ZZ \to $ four charged leptons channel.
