 New physics searches in the top quark sector (excluding ttbar resonance searches) / Das, Pallabi (TIFR, Mumbai, DHEP) /ATLAS ,CMS and Top Collaborations Several theories beyond the Standard Model of Particle Physics predict new and heavy particles yet to be observed in the hadron colliders. These particles are likely to decay through the heavy top quark, making it suitable as a probe for new physics phenomena. [...] CMS-CR-2017-031.- Geneva : CERN, 2017 - 7 p.

 Flavor Changing Neutral Current searches in the top quark sector / Bhowmik, Sandeep (Bhubaneswar, NISER) /ATLAS ,CMS and Top Collaborations Flavor changing neutral current (FCNC) interactions in top quark are highly suppressed in the Standard Model. Therefore, any measurable branching ratio for top FCNC decays is an indication of new physics. [...] CMS-CR-2017-097.- Geneva : CERN, 2017 - 8 p.
