Jet substructure has emerged to play a central role at the Large Hadron Collider, where it provided numerous innovative ways search for new physics and probe Standard Model, particularly in extreme regions of phase space. In this article we focus on review development use state-of-the-art jet techniques by ATLAS CMS experiments.
This report of the BOOST2012 workshop presents results four working groups that studied key aspects jet substructure. We discuss potential first-principle QCD calculations to yield a precise description substructure jets and study accuracy state-of-the-art Monte Carlo tools. Limitations experiments' ability resolve are evaluated, with focus on impact additional (pile-up) proton collisions performance in future LHC operating scenarios. A final section summarizes lessons learnt from analyses...
The axion emerges in extensions of the Standard Model that explain absence CP violation strong interactions. Simultaneously, it can provide naturally cold dark matter our universe. Several searches for axions and axion-like particles (ALPs) have constrained corresponding parameter space over last decades but no unambiguous hints their existence been found. mass range below 1 meV remains highly attractive a well motivated region axions. In this White Paper we present description new...
This Report summarises the activities of "SM and Higgs" working group for Workshop "Physics at TeV Colliders", Les Houches, France, 2-20 May, 2005. On one hand, we performed a variety experimental theoretical studies on standard candles (such as W, Z, ttbar production), treating them either proper signals known physics, or backgrounds to unknown physics; also addressed issues relevant those non-perturbative semi-perturbative ingredients, such Parton Density Functions Underlying Events, whose...

The photon asymmetry in the reaction 1H(--> gamma,pi(0))(1)H close to threshold has been measured for first time with spectrometer TAPS using linearly polarized photons from tagged-photon facility at Mainz Microtron MAMI. total and differential cross sections were also simultaneously asymmetry. This allowed determination of S-wave all three P-wave amplitudes. values obtained are E(0+) = [-1.33+/-0.08(stat)+/-0.03(syst)] x 10(-3)/m(pi(+)), P(1) [9.47 +/- 0.08(stat) 0.29(syst)]...
The reaction $\ensuremath{\gamma}p\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{0}n$ has been measured at MAMI for photon energies up to 820 MeV. Invariant mass spectra of the particles in final state $({\ensuremath{\pi}}^{+}n)$, $({\ensuremath{\pi}}^{0}n)$, $({\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{0})$ have determined several bins incident energy. Differences ${\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{0}$ and simultaneously...
The U(1) gauge-Higgs model with two flavors of opposite charge and a chemical potential is mapped exactly to dual representation where matter fields correspond loops flux the gauge are represented by surfaces. complex action problem conventional formulation at finite μ overcome in representation, partition sum has only real nonzero contributions. We simulate using generalized worm algorithm, explore phase diagram, study condensation phenomena μ.
First 7 TeV proton-proton collisions produced by the Large Hadron Collider at CERN have been recorded CMS experiment in 2010.The ability to accurately and efficiently reconstruct trajectories of charged particles these is a critical component for most measurements LHC.Several methods determining efficiency measuring resolution track parameters using first data collected detector are presented.The key elements reconstruction primary interaction vertex identification jets containing products...
Abstract The reciprocity approach is a powerful method to determine the expected signal power of axion haloscopes in model-independent way. Especially for open and broadband setups like MADMAX dielectric haloscope sensitivity field difficult calibrate since they do not allow discrete eigenmode analysis are optically too large fully simulate. central idea measure reflection-induced test setup instead trying simulate axion-induced field. In this article, used dish antenna minimal directly from...
We analyze properties of local Polyakov loops using quenched as well dynamical SU(3) gauge configurations for a wide range temperatures. It is demonstrated that both, the confined and deconfined regime, loop prefers phase values near center elements 1,e±i2π/3. divide lattice sites into three sectors according to these phases show give rise formation clusters. For suitable definition clusters we find in case deconfinement manifests itself onset percolation A possible continuum limit discussed.
Recent effort related to cognitive radio systems has lead an in-depth analysis of context information management and exploitation based on a control channel for enhancement needed for, say, suitable link selection in heterogeneous framework, dynamic resource management, distributed sensing. Concerning the actual implementation such CCC, focus was recently moved toward in-band solution, where is transported building existing access technologies. In this scope, article illustrates relevant...
