Search for direct third-generation squark pair production in final states with missing transverse momentum and two b-jets in √s=8 TeV pp collisions with the ATLAS detector [PDF]

open access: yes, 2013
The results of a search for pair production of supersymmetric partners of the Standard Model third-generation quarks are reported. This search uses 20.1 fb−1 of pp collisions at √s=8 TeV collected by the ATLAS experiment at the Large Hadron Collider. The

Very large lepton collider in the Very Large Hadron Collider tunnel

open access: yesPhysical Review Special Topics. Accelerators and Beams, 2002
The Very Large Hadron Collider design is converging on a program where a 233 km circumference tunnel would first be occupied by a low field dipole system producing 40 TeV in the center of mass, followed by a higher field magnet system producing nearly ...

Search for new phenomena in final states with large jet multiplicities and missing transverse momentum at s√=8 TeV proton-proton collisions using the ATLAS experiment [PDF]

open access: yes, 2013
A search is presented for new particles decaying to large numbers (7 or more) of jets, with missing transverse momentum and no isolated electrons or muons. This analysis uses 20.3 fb−1 of pp collision data at s√=8 TeV collected by the ATLAS experiment at

Status of LHC Searches for SUSY without R-Parity

open access: yesAdvances in High Energy Physics, 2015
In this contribution we briefly review the status of current searches for supersymmetry at the Large Hadron Collider, focusing especially on viable sub-TeV colored superpartners which can appear in nonstandard scenarios.

Operational results with fast automatic beam-based LHC collimator alignment [PDF]

open access: yes, 2013
The CERN Large Hadron Collider (LHC) is the largest and highest-energy particle accelerator ever built. It is designed to collide particles at a centre-of-mass energy of 14 TeV to explore the fundamental forces and constituents of matter.

Luminosity optimization near the beam-beam limit by increasing bunch length or crossing angle

open access: yesPhysical Review Special Topics. Accelerators and Beams, 2002
We discuss the choice of bunch length and crossing angle near the beam-beam limit in a storage-ring collider. First, we derive expressions for the tune shifts of either bunched or continuous round beams which are induced by a single collision with ...

Measurement of the top quark charge in pp collisions at s√=7 TeV with the ATLAS detector [PDF]

open access: yes, 2011
A measurement of the top quark electric charge is carried out in the ATLAS experiment at the Large Hadron Collider using 2.05 fb−1 of data at a centre-of-mass energy of 7 TeV. In units of the elementary electric charge, the top quark charge is determined

Overview on Heavy-Flavour at RHIC and LHC

open access: yesProceedings, 2019
The PHENIX and STAR Collaborations at the Relativistic Heavy-Ion Collider and ALICE, CMS, ATLAS and LHCb Collaborations at the Large Hadron Collider have measured the production of charmonium and bottonium states as well as open heavy flavor hadrons via ...
