Measurement of the Tau topological branching ratios

P. Abreu, +253 more
TL;DR: In this article, measurements of the inclusive T branching ratios for decay modes containing one, three, or five charged particles have been performed, giving the following results: B-1 equivalent to B T- (particle)(-) greater than or equal to0 pi (0) greater than and equal to 0K(0) v(T) (v(overbar)) = 85.316 +/- 0.049) %; B-3 equivalent to b(T- → 2h(-)h(+) greater than 0π(1)-1.569

Georges Aad, +3071 more
- 01 Jul 2011 - 
TL;DR: In this article, a search for contact interactions was performed using dimuon events recorded with the ATLAS detector in proton-proton collisions at root s = 7 TeV.
Journal ArticleDOI

Erratum to: "Search for first generation scalar leptoquarks in pp collisions at s=7TeV with the ATLAS detector" [Phys. Lett. B 709 (2012) 158]

Georges Aad, +3114 more
- 23 May 2012 - 
TL;DR: Weerts et al. as mentioned in this paper corrected the legend of the y-axis of Fig 4 to read σ ( pp → LQLQ ) as shown in the corrected Fig 4 attached, rather than σ × BR.
Journal ArticleDOI

A Measurement of the tau Leptonic Branching Fractions

P. Abreu, +550 more
- 14 Sep 1995 - 
TL;DR: In this article, a sample of 25000 Z0 → τ+τ− events collected by the DELPHI experiment at LEP in 1991 and 1992 was used to measure the leptonic branching fractions of the τ lepton.
Journal ArticleDOI

Measurement of the B0B0 mixing parameter in DELPHI

P. Abreu, +553 more
- 21 Jul 1994 - 
TL;DR: In this paper, a total of about View the MathML source decays have been analyzed to measure the view-the-MathML source mixing probability, and two different b tagging techniques have been used: events with two leptons and events with one lepton and one Λ.
