We have investigated the northeasterly/southwesterly wind jets blowing through the Tsushima Strait from two case studies. Using high-resolution winds derived from SAR, we have presented the detailed structure of wind in the strait. The general flow is generally close to geostrophic wind in the strait, inferring from the seal level pressure fields. Wind jets are induced by two channels and by th...
Higgs boson production in association with two tagging jets will be mediated by electroweak vector boson fusion and by gluon fusion. For the gluon fusion process, analysis of the azimuthal angle correlations of the two jets provides for a direct measurement of the CP-nature of the Htt Yukawa coupling which is responsible for the effective Hgg vertex. HJJ PRODUCTION: SIGNALS AND CP MEASUREMENTS ...
Tree-level studies have shown in the past that kinematical correlations between the two jets in Higgs+2-jet events are direct probes of the Higgs couplings, e.g. of their CP nature. In this paper we explore the impact of higher-order corrections on the azimuthal angle correlation of the two leading jets and on the rapidity distribution of extra jets. Our study includes matrix-element and shower...
The jets observed to emanate from many compact accreting objects may arise from the twisting of a magnetic field threading a differentially rotating accretion disk which acts to magnetically extract angular momentum and energy from the disk. Two main regimes have been discussed, hydromagnetic jets, which have a significant mass flux and have energy and angular momentum carried by both matter an...
in this paper meteorological conditions of some acute air pollution periods for the city of tehran have been considered. the data used were obtained from the air quality control company (aqcc) of municipality and from synoptic station of the institute of geophysics. initially some statistical methods were used to find the episodes for acute air pollution episodes, and then their meteorological ...
Three jets events in the ee collisions at 91.2 GeV are investigated using both HERWIG and JETSET Monte Carlo generators. The angles between the three jets are used to identify the quark and gluon jets. The analysis at parton level is done to ensure the reasonableness of this method and an angular cut is ultilized to improve the purity of this identification. The multiplicity inside the identifi...

We deduce a classification of all special types of nonholonomic 3-jets. In the introductory part, we summarize the basic properties of nonholonomic r-jets. Generally speaking, a very attractive phenomenon of the problem of classifying the special types of nonholonomic 3-jets is that its solution is heavily based on the Weil algebra technique, even though no algebras appear in the formulation of...
Measurement of the top quark mass in the t ¯ t → lepton+jets and t ¯ t → dilepton channels using √ s = 7 TeV ATLAS data Abstract The top quark mass was measured in the channels t ¯ t → lepton+jets and t ¯ t → dilepton (lepton = e, μ) based on ATLAS data recorded in 2011. The data were taken at the LHC with a proton–proton centre-of-mass energy of √ s = 7 TeV and correspond to an integrated lumi...
