Abstract

In this study, the first fast-timing measurements from nuclides produced via the in-flight fission mechanism are reported. The lifetimes of the first 2⁺ states in ^104,106Zr nuclei have been measured via β-delayed γ-ray timing of stopped radioactive isotope beams. An improved precision for the lifetime of the 2⁺₁ in ¹⁰⁴Zr was obtained, τ(2⁺₁) = 2.90⁺²⁵_–20, as well as a first measurement of the 2⁺₁ state in ¹⁰⁶Zr, τ(2⁺₁) = 2.60⁺²⁰_–15 ns, with corresponding reduced transition probabilities.

Measurement of the differential $γ + 2 b$ -jet cross section and the ratio $σ (γ + 2 b -jets) / σ (γ + b -jet)$ in $p \bar{p}$ collisions at $\sqrt{s} = 1.96 TeV$

Journal Article Abazov, V. M. ; Abbott, B. ; Acharya, B. S. ; ... - Physics Letters B

We present the first measurements of the differential cross section dσ/dp^γ_Τ for the production of an isolated photon in association with at least two b-quark jets. The measurements consider photons with rapidities |y^γ | < 1.0 and transverse momenta 30 < p^γ_Τ < 200 GeV. The b-quark jets are required to have p^jet_Τ > 15 GeVand |γ^jet| < 1.5. The ratio of differential production cross sections for γ + 2 b-jets to γ +b-jet as a function of p^γ_Τ is also presented. The results are based on the proton–antiproton collision data at √s = 1.96 TeV collected with the D0more »« less

Measurement of exclusive $γ γ \to ℓ^{+} ℓ^{-}$ production in proton–proton collisions at $\sqrt{s} = 7 TeV$ with the ATLAS detector

Journal Article Aad, G. ; Abbott, B. ; Abdallah, J. ; ... - Physics Letters B

This paper reports a measurement of the exclusive γγ→ℓ⁺ℓ^- (ℓ=e, μ) cross-section in proton–proton collisions at a centre-of-mass energy of 7 TeV by the ATLAS experiment at the LHC, based on an integrated luminosity of 4.6 fb^-1. For the electron or muon pairs satisfying exclusive selection criteria, a fit to the dilepton acoplanarity distribution is used to extract the fiducial cross-sections. The cross-section in the electron channel is determined to be σmore »« less

Journal Article Adam, J. ; Adamová, D. ; Aggarwal, M. M. ; ... - Physics Letters B

© 2016 CERN for the benefit of the ALICE Collaboration. The production of the hypertriton nuclei HΛ3 and H[U+203E]Λ-3 has been measured for the first time in Pb-Pb collisions at sNN=2.76 TeV with the ALICE experiment at LHC. The p T -integrated HΛ3 yield in one unity of rapidity, dN/dy×B.R.(HΛ3→He3,π-)=(3.86±0.77(stat.)±0.68(syst.))×10-in the 0-10% most central collisions, is consistent with the predictions from a statistical thermal model using the same temperature as for the light hadrons. The coalescence parameter B 3 shows a dependence on the transverse momentum, similar to the B 2 of deuterons and the B 3 of 3 Hemore »« less
