“…Implication to the Cesium atom gives constraints on mass of the extra neutral gauge boson Z ′ and on the mixing angles W − Y and Z − Z ′ . The lower mass limit for Z ′ is 564 GeV which coincide with the recent direct search constraints at CDF [14], D0 [15] and in agreement with various bounds given in [12]. The upper mixing angle limits for |θ| and |ϕ| depend on the quark content.…”

The deviation δQ W of the weak charge from its standard model prediction due to the mixing of the W boson with the charged bilepton Y as well as of the Z boson with the neutral Z ′ and the real part of the non-Hermitian neutral bilepton X in the economical 3-3-1 model is established. Additional contributions to the usual δQ W expression in the extra U(1) models and the left-right models are obtained. Our calculations are quite different from previous analyzes in this kind of the 3-3-1 models and give the limit on mass of the Z ′ boson, the Z − Z ′ and W − Y mixing angles with the more appropriate values: M Z ′ > 564 GeV, −0.018 < sin ϕ < 0 and | sin θ| < 0.043.

“…The possibility that parton showering and hadronization may influence the power index n is revealed by the measurements of the transverse differential cross section of hadron and photon jets for pp collisions at Fermilab by the CDF and D0 collaborations [49][50][51][52][53]. In these measurements, the power indices n are found to be close to n=4-5 (see Fig.…”

“…Indeed, comparison with the experimental power indices in the transverse differential cross sections for jet production supports the approximate validity of a basic α 2 s /c 4 T behavior for parton-parton collisions in relativistic hardscattering processes. As a hadron jet or a photon jet corresponds to the state of a parton after a parton-parton collision but before the final-state showering, we now understand that the systematic difference between the power index of n∼4-5 for jets [21,[49][50][51][52][53]61], and n∼6-7 for hadrons [33] may be attributed to the subsequent showering and hadronization of the parton jet to hadron fragments of lower transverse momenta. Another part of the increase of the power index arises from the p T dependence of the structure function factor (1 − x a0 ) g (1 − x b0 ) g and the running coupling constant.…”

Tsallis fits topTspectra and multiple hard scattering inppcollisions at the LHC

Phenomenological Tsallis fits to the CMS, ATLAS, and ALICE transverse momentum spectra of hadrons for pp collisions at LHC were recently found to extend over a large range of the transverse momentum. We investigate whether the few degrees of freedom in the Tsallis parametrization may arising from the relativistic parton-parton hard-scattering and related processes. The effects of the multiple hard-scattering and parton showering processes on the power law are discussed. We find empirically that whereas the transverse spectra of both hadrons and jets exhibit power-law behavior of 1/p n T at high pT , the power indices n for hadrons are systematically greater than those for jets, for which n∼4-5.

These proceedings outline steps toward a systematic analysis of frontier energy collider data: specifically, those data collected at Tevatron Runs I and II, LEP Run II, HERA Runs I and II, and the future LHC. Algorithms designed to understand the gross features of the data (Vista), to systematically and model-independently search for new physics at the electroweak scale (Sleuth), to automate tests of specific hypotheses against those data (Quaero), to turn an existing full detector simulation into a fast simulation (TurboSim), and to infer the physics underlying any hint observed in the data (Bard) are reviewed. A somewhat non-conventional viewpoint is adopted throughout.
