Searches for Fourth Generation Fermions
A. Ivanov for CDF, D0 Collaborations
TL;DR
This paper reports on searches for hypothetical fourth-generation fermions using data from Fermilab's Tevatron collider, setting the most stringent limits to date on their possible masses.
Contribution
It provides new experimental limits on fourth-generation fermion masses based on collider data, improving constraints over previous studies.
Findings
Most stringent 95% C.L. limits on fermion masses to date
No evidence found for fourth-generation fermions
Enhanced understanding of fermion mass constraints
Abstract
We present the results from searches for fourth generation fermions performed using data samples collected by the CDF II and D0 Detectors at the Fermilab Tevatron ppbar collider. Many of these results represent the most stringent 95% C.L. limits on masses of new fermions to-date.
