Search for the decay K+→π+γγ in the π+ momentum region P>213 MeV/c

A. Artamonov, +63 more
- 15 Sep 2005 - 
TL;DR: In this paper, an upper bound on the partial branching ratio of 2.3 x 10{sup -9} at the 90% confidence level was obtained, under the assumption of chiral perturbation theory including next-to-leading order ''unitarity'' corrections.
Journal ArticleDOI

Study of heavy-flavor quarks produced in association with top-quark pairs at s =7TeV using the ATLAS detector

Georges Aad, +2921 more
- 21 Apr 2014 - 
TL;DR: In this article, a study of the production of top-quark pairs together with heavy-flavor quarks, collectively referred to as (tt) over bar + HF, was performed.
Journal ArticleDOI

Measurements of the electron drift velocity and positive-ion mobility for gases containing CF4

T. Yamashita, +13 more
- 10 Nov 1989 - 
TL;DR: In this paper, the electron drift velocity and positive ion mobility for gases containing CF 4 have been measured and the results are presented for four types of gas mixtures: CF 4 + CH 4, CF 4+C 2 H 6, CF4+C 3 H 8 and CF4 +iso-C 4 H 10.
Journal ArticleDOI

Search for top-quark decays t → Hq with 36 fb−1 of pp collision data at √S = 13 TeV with the ATLAS detector

Morad Aaboud, +2966 more
- 21 May 2019 - 
TL;DR: In this paper, a search for flavour-changing neutral current decays of a top quark into an up-type quark and the Standard Model Higgs boson, t Hq, is presented.
Journal ArticleDOI

Determination of spin and parity of the Higgs boson in the WW∗ →eνμν decay channel with the ATLAS detector

Georges Aad, +2826 more
- 27 May 2015 - 
TL;DR: In this article, the spin and parity quantum numbers of the Higgs boson in the final state are presented, based on proton-proton collision data collected by the ATLAS detector at the Large Hadron Collider, corresponding to an integrated luminosity of 20.3 fb.
