Precise measurement of the top quark mass in the dilepton channel at D0 | D0 Collaboration
; V. Abazov
; | Date: |
2 May 2011 | Abstract: | We measure the top quark mass (mt) in ppbar collisions at a center of mass
energy of 1.96 TeV using dilepton ttbar->W+bW-bbar->l+nubl-nubarbbar events,
where l denotes an electron, a muon, or a tau that decays leptonically. The
data correspond to an integrated luminosity of 5.4 fb-1 collected with the D0
detector at the Fermilab Tevatron Collider. We obtain mt = 174.0 +- 1.8(stat)
+- 2.4(syst) GeV, which is in agreement with the current world average mt =
173.3 +- 1.1 GeV. This is currently the most precise measurement of mt in the
dilepton channel. | Source: | arXiv, 1105.0320 | Services: | Forum | Review | PDF | Favorites |
