Description
Color reconnection constitutes one of the main limiting factors for the
high-precision top-mass measurements at hadron colliders.
This talk will describe what color reconnection is, how it is modeled in
event generators and how it affects the reconstruction of
top final states, with a particular emphasis on the top mass.
A series of new color reconnection models implemented in Pythia 8 will be
presented, focusing on their implications for the existing top mass
measurements and demonstrating ways in which future
measurements could be used to constrain them.
