 **Motivations and goal**
-  * Exotic decays such as  $\rho \to T t$  can eat branching ratio from standard search channels (dilepton, dibosons), rendering these direct searches less sensitive (see [[https://arxiv.org/pdf/1511.01101.pdf]] Fig. 3

-  * Investigate the signatures arising from the decay of a heavy bosons (spin 0 and spin 1) in SM quarks and VLQs, e.g. Z'-> VLQ top, ora extra light scalars, e.g. Z' -> Z a

 **Strategies**
-  * Categorize the possible decays
+  * Categorize the possible decays of the identified resonances. This was done for VLQ in Les Houches 2015

+  * Check the sensitivity of SM searches. For example the  $\rho \to T \bar t \to Z t \bar t$  has the same final state of the SM  $t\bar t Z$  search
+  * Check the sensitivity of single production mode. Also in this case the final state can be the same. However single production searches usually exploit a forward jet, which is not present here

 **Further questions**
   * From the polarization of the top arising from the decay is it possible to infer the representation to which the heavy boson belongs, i.e. predict the presence of other states?
