Cycle-continuous mappings -- order structure
Robert Šámal
Given two graphs, a mapping between their edge-sets is cycle-continuous, if the preimage of every cycle is a cycle. The motivation for this notion is Jaeger's conjecture that for e…
Conformal infinity in Robinson-Trautman spacetimes with cosmological constant
Otakar Svitek
In past, the future asymptotic behavior (with respect to initial data on null hypersurface) of Robinson-Trautman spacetime was examined and its past horizon characterized. Therefor…
Recursion Relations for Tree-level Amplitudes in the SU(N) Non-linear Sigma Model
Karol Kampf, Jiri Novotny, Jaroslav Trnka
It is well-known that the standard BCFW construction cannot be used for on-shell amplitudes in effective field theories due to bad behavior for large shifts. We show how to solve t…
Constraints on the origin of cosmic rays above eV from large scale anisotropy searches in data of the Pierre Auger Observatory
Pierre Auger Collaboration
A thorough search for large scale anisotropies in the distribution of arrival directions of cosmic rays detected above eV at the Pierre Auger Observatory is reported. For…
Comment on `Determination of light quark masses from '
Martin Zdráhal
In the commented paper [PRD 78, 034032 (2008); arXiv:0803.2956] Deandrea et al. claim that they provide a model-independent determination of the quantity based on th…
Measurement of the t t-bar production cross section in pp collisions at sqrt(s) = 7 TeV with lepton + jets final states
CMS Collaboration
A measurement of the t t-bar production cross section in pp collisions at sqrt(s) = 7 TeV is presented. The results are based on data corresponding to an integrated luminosity of 2…
