T. Han, D. Rainwater, D. Zeppenfeld (University of Wisconsin -, Madison)
TL;DR
This paper investigates the potential to detect large extra dimensions at hadron colliders through the Drell-Yan process with missing energy, setting exclusion limits on the gravity scale based on collider data.
Contribution
It provides new sensitivity estimates for large extra dimensions at Tevatron and LHC using the Drell-Yan process with missing energy signatures.
Findings
Exclusion limits up to 560 GeV at Tevatron
Limits up to 4.0 TeV at LHC for 3 extra dimensions
Limits up to 3.3 TeV at LHC for 4 extra dimensions
Abstract
We explore the search sensitivity for signals of large extra dimensions at hadron colliders via the Drell-Yan process pp -> l+ l- + E_T(miss) X (l = e,mu) where the missing transverse energy is the result of escaping Kaluza-Klein gravitons. We find that one is able to place exclusion limits on the gravity scale up to 560 GeV at the Fermilab Tevatron, and to 4.0 (3.3) TeV at the CERN LHC, for n = 3 (4) extra dimensions.
