Jet energy measurement with the ATLAS detector in proton-proton collisions at sqrt(s) = 7 TeV
ATLAS Collaboration
The jet energy scale (JES) and its systematic uncertainty are determined for jets measured with the ATLAS detector at the LHC in proton-proton collision data at a centre-of-mass en…
Quantum graphs with singular two-particle interactions
Jens Bolte, Joachim Kerner
We construct quantum models of two particles on a compact metric graph with singular two-particle interactions. The Hamiltonians are self-adjoint realisations of Laplacians acting…
Spin Ice, Fractionalization and Topological Order
C. Castelnovo, R. Moessner, S. L. Sondhi
The spin ice compounds {\dys} and {\holm} are highly unusual magnets which epitomize a set of concepts of great interest in modern condensed matter physics: their low-energy physic…
An Identity for Kernel Ridge Regression
Fedor Zhdanov, Yuri Kalnishkan
This paper derives an identity connecting the square loss of ridge regression in on-line mode with the loss of the retrospectively best regressor. Some corollaries about the proper…
Measurement of inclusive jet and dijet production in pp collisions at sqrt(s) = 7 TeV using the ATLAS detector
ATLAS Collaboration
Inclusive jet and dijet cross sections have been measured in proton-proton collisions at a centre-of-mass energy of 7 TeV using the ATLAS detector at the Large Hadron Collider. The…
Search for heavy vector-like quarks coupling to light quarks in proton-proton collisions at sqrt(s) = 7 TeV with the ATLAS detector
ATLAS Collaboration
This letter presents a search for singly produced vector-like quarks, Q, coupling to light quarks, q. The search is sensitive to both charged current (CC) and neutral current (NC)…
Triangulations of the sphere, bitrades and abelian groups
Simon R. Blackburn, Thomas A. McCourt
Let be a triangulation of the sphere with vertex set , such that the faces of the triangulation are properly coloured black and white. Motivated by applications in the theor…
Observation of a new chi_b state in radiative transitions to Upsilon(1S) and Upsilon(2S) at ATLAS
ATLAS Collaboration
The chi_b(nP) quarkonium states are produced in proton-proton collisions at the Large Hadron Collider (LHC) at sqrt(s) = 7 TeV and recorded by the ATLAS detector. Using a data samp…
Search for first generation scalar leptoquarks in pp collisions at sqrt(s) = 7 TeV with the ATLAS detector
ATLAS Collaboration
We report a search for first generation scalar leptoquarks using 1.03 fb^-1 of proton-proton collisions data produced by the Large Hadron Collider at sqrt(s)=7 TeV and recorded by…

ATLAS Collaboration
This paper reports a measurement of D*+/- meson production in jets from proton-proton collisions at a center-of-mass energy of sqrt(s) = 7 TeV at the CERN Large Hadron Collider. Th…
B0 meson decays to rho0 K*0, f0 K*0, and rho-K*+, including higher K* resonances
The BABAR Collaboration
We present branching fraction measurements for the decays B0 -> rho0 K*0, B0 -> f0 K*0, and B0 -> rho- K*+, where K* is an S-wave (K pi)_0* or a K*(892) meson; we also measure B0 -…

ATLAS Collaboration
The results of a search for pair production of the scalar partners of bottom quarks in 2.05 fb^-1 of pp collisions at sqrt{s} = 7 TeV using the ATLAS experiment are reported. Scala…

ATLAS Collaboration
This Letter describes a model-independent search for production of new resonant states in photon-jet events in 2.11 fb^-1 of proton-proton collisions at sqrt(s) = 7 TeV. We compare…
A field trip through spin ice
G. Sala, C. Castelnovo, R. Moessner +5
Fractionalisation -- the breaking up of an apparently indivisible microscopic degree of freedom -- is one of the most counterintuitive phenomena in many-body physics. Here we study…
Search for the Higgs boson in the H->WW(*)->lvlv decay channel in pp collisions at sqrt(s) = 7 TeV with the ATLAS detector
ATLAS Collaboration
A search for the Higgs boson has been performed in the H->WW->lvlv channel (l=e/mu) with an integrated luminosity of 2.05/fb of pp collisions at sqrt(s) = 7 TeV collected with the…
On Problems as Hard as CNFSAT
Marek Cygan, Holger Dell, Daniel Lokshtanov +6
The field of exact exponential time algorithms for NP-hard problems has thrived over the last decade. While exhaustive search remains asymptotically the fastest known algorithm for…
Search for extra dimensions using diphoton events in 7 TeV proton-proton collisions with the ATLAS detector
ATLAS Collaboration
Using data recorded in 2011 with the ATLAS detector at the Large Hadron Collider, a search for evidence of extra spatial dimensions has been performed through an analysis of the di…
High-Fidelity Polarization Storage in a Gigahertz Bandwidth Quantum Memory
D. G. England, P. S. Michelberger, T. F. M. Champion +8
We demonstrate a dual-rail optical Raman memory inside a polarization interferometer; this enables us to store polarization-encoded information at GHz bandwidths in a room-temperat…
