Phys. Rev. Lett. 108, 101801 – Published 7 March 2012


In this Letter, we present a precise measurement of the total ZZ production cross section in pp¯ collisions at s=1.96TeV, using data collected with the CDF II detector corresponding to an integrated luminosity of approximately 6fb1. The result is obtained by combining separate measurements in the four-charged () and two-charged-lepton and two-neutral-lepton (νν) decay modes of the Z boson pair. The combined measured cross section for pp¯ZZ is 1.640.38+0.44pb. This is the most precise measurement of the ZZ production cross section in 1.96 TeV pp¯ collisions to date.

Heating up of Superconductors
January 27, 2017

This collection marks the 30th anniversary of the discovery of high-temperature superconductors. The papers selected highlight some of the advances that have been made to date, both in understanding why these compounds behave in the way they do, and in utilizing them in applications. The papers included in the collection have been made free to read.

APS and CERN Sign Open Access Agreement for SCOAP3

APS and CERN, the host organization of SCOAP3 (Sponsoring Consortium for Open Access Publishing in Particle Physics), have signed an agreement to make the high-energy physics (HEP) articles published in three leading APS journals open access beginning January 1, 2018. This agreement acts to support the publishing of open access content for wider benefit of the HEP community.
