Searches for vector-like quarks and resonances decaying to top quarks with the ATLAS and CMS detectors / Van Onsem, Gerrit Patrick (DESY) /ATLAS and CMS Collaborations
Many models beyond the standard model predict the existence of vector-like quarks or other types of heavy resonances. Using proton-proton collision data at center-of-mass energies of 8 and 13 TeV, the ATLAS and CMS Collaborations have performed a multitude of searches for pair and singly produced vector-like quarks decaying to W, Z, or Higgs bosons.

Differential cross sections of global event variables of $t\bar t$ / Kim, Tae Jeong (Hanyang U.) /ATLAS ,CMS and Top Collaborations
During the Run 2 period of the LHC, the ATLAS and CMS experiments have accumulated proton-proton collision data corresponding to an integrated luminosity of around 3 fb$^{-1}$ in 2015 and 36 fb$^{-1}$ in 2016 at a center of mass energy of 13 TeV. In the journey of finding new physics, it is of importance to understand the standard model which seems to be complete after the Higgs discovery. Precision tests must be performed in every corner of the phase space since new physics can appear in any different places. In this proceedings, measurements of the differential cross sections of global event variables from the top quark pair productions at the both experiments using the data collected during the Run 2 period by the time of the year 2016 are presented..
