ttX and top properties in ATLAS and CMS / Alvarez Gonzalez, Barbara (Oviedo U.) /ATLAS and CMS Collaborations
The top quark offers a very rich physics program. This talk focuses on searches for flavor-changing neutral-current (FCNC) and on measurements and searches for rare top production modes, the so called ttX processes. [...]
