DESCRIPTION:The top quark\, its couplings\, and its properties\, serve as 
 excellent probes of the SM. Due to its high mass\, it is the only quark th
 at decays before hadronisation\; enabling its study through its decay prod
 ucts. Production of a top quark pair in association with a W boson is one 
 of the most intriguing SM processes to date. Aside from the cross--section
  discrepancy between the theoretical prediction and the latest LHC measure
 ments\, the emittance of the $W$ boson from the initial state grants it so
 me unique characteristics. These can be probed using final--state observab
 les that target angular properties\, such as the central--forward asymmetr
 y $A_{C}^{\\ell}$ based on the absolute pseudorapidity difference of the 
 charged leptons decaying from the top quark pair. Moreover\, new physics e
 ffects can be encapsulated within additional degrees of freedom in the con
 text of an EFT extension of the SM. Distinctively\, the top quark has the 
 potential to strongly couple to new physics objects above the threshold sc
 ale $\\Lambda=1$ TeV\, which could be conducive to deviations of the SM p
 redictions in some experimental observables. \n\nhttps://indico.ific.uv.e
