ILC Reference Design Report Volume 3 - Accelerator

Robin Erbacher, +1810 more
- 14 Dec 2007 - 
TL;DR: The International Linear Collider (ILC) is a 200-500 GeV center-of-mass high-luminosity linear electron-positron collider, based on 1.3 GHz superconducting radio-frequency (SCRF) accelerating cavities.
Journal ArticleDOI

Search for vector-like quarks in events with two oppositely charged leptons and jets in proton-proton collisions at √s = 13 TeV

Albert M. Sirunyan, +2253 more
- 26 Apr 2019 - 
TL;DR: Lower limits at 95% confidence level are placed on the masses of the T and B quarks for a range of branching fractions, consistent with standard model background estimations.
Journal ArticleDOI

Observation of Correlated Azimuthal Anisotropy Fourier Harmonics in pp and p+Pb Collisions at the LHC.

Albert M. Sirunyan, +2205 more
- 26 Feb 2018 - 
TL;DR: The azimuthal anisotropy Fourier coefficients (v_{n}) in 8.16 TeV p+Pb data are extracted via long-range two-particle correlations as a function of the event multiplicity and compared to corresponding results in pp and PbPb collisions, finding the v_{2} and v_{4} coefficients to be positively correlated in all collision systems.
Journal ArticleDOI

Measurement of beauty production in deep inelastic scattering at HERA

Sergei Chekanov, +343 more
- 14 Oct 2004 - 
TL;DR: In this article, the beauty production cross section for deep inelastic scattering events with at least one hard jet in the Breit frame together with a muon has been measured, for photon virtualities Q2>2 GeV2, with the ZEUS detector at HERA using integrated luminosity of 72 pb-1.
Journal ArticleDOI

Search for narrow high-mass resonances in proton-proton collisions at √s = 8 TeV decaying to a Z and a Higgs boson

Vardan Khachatryan, +2137 more
- 02 Sep 2015 - 
TL;DR: In this article, a search for a narrow, high-mass resonance decaying into Z and Higgs (H) bosons is presented, where the final state consists of a merged jet pair and a τ pair resulting from the decays of Z andH bosons, respectively.
