This talk presents the analyses results of the diboson (WW or WZ) resonances production search in pp collisions at √s = 8 and 13 TeV with the ATLAS detector at the LHC with the semileptonic final state. As benchmark signal models Randall-Sundrum bulk model for KK G* → WW and Heavy Vector Triplet model for W′ → WZ and Z′ → WW are used. No significant excess for diboson resonances production is observed and upper limits on the production cross section times branching fraction of G*, W′ and Z′ are determined at 95% CL. 相似文献

The spectra of p, d, and t charged particles produced in stopped-pion absorption by nuclei are analyzed. Respective measurements were performed for 17 nuclei by means of a semiconductor spectrometer. A phenomenological model developed previously for medium-heavy and heavy nuclei was applied to describing the spectra and yields of charged particles originating from light nuclei (6,7Li, 9Be, 10,11B, and 12C). The contribution of intranuclear clusters (such as pp and 3,4He) to pion absorption was estimated. 相似文献

Two crystal modifications (m-1 and m-2) of the mixed-ligand complex ZnPhen(i-PrOCS2)2 have been isolated. Their crystal structures were solved using X-ray diffraction data (CAD-4 diffractometer, MoK radiation, 3141 and 3532 Fhkl, R = 0.0363 and 0.0304). For both modifications, the crystals are monoclinic with unit cell parameters a = 10.543(2), b = 13.494(3), c = 16.875(3) , = 102.08(3)°, V = 2347.6(8) 3, Z = 4, space group P21/n (m-1) and a = 10.931(2), b = 12.996(3), c = 16.288(3) , = 92.69(3)°, V = 2311.3(8) 3, Z = 4, space group P21/n (m-2). The structures basically consist of discrete monomer molecules in which the Zn atom has a tetragonal pyramidal (m-1: ZnN2S3, c.n. 5, bidentate and monodentate i-PrOCS

A method is described for the preparation of 1,3-diacetylferrocene, in which ethylferrocene is first acetylated with acetyl chloride in the presence of AlCl3 in methylene chloride to a mixture of isomeric acetylethylferrocenes. This mixture is then subjected to thin-layer chromatography, a mixture of the 1,1′- and 1,3-derivatives free from the 1,2-isomer being obtained. After oxidation of this mixture with MnO2 to a mixture of 1,1′- and 1,3-diacetylferrocenes, the isomers are separated by preparative thin-layer chromatography. 相似文献

New 3-bromo and 1,4-diaminomethyl derivatives of 4-aminopyrazolo[3,4-d]pyrimidine were obtained by bromination and aminomethylation, respectively. 4-Bromopyrazolo[3,4-d]pyrimidines were synthesized for the first time by diazotization of 4-aminopyrazolo[3,4-d]pyrimidines.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 7, pp. 982–984, July, 1982. 相似文献

The proton magnetic resonance spectra for ferrocene derivatives have been investigated in the solid state at a frequency of 27.5 MHz and at temperatures within the range 4.2–300 K. Evidence for re-orientation in various substituent groups and cyclopentadienyl rings has been deduced on the basis of the temperature dependence of the second moment of the PMR lines. The experimentally observed decrease in the second moment has been compared with the calculated contributions of different molecular groups to the second moment thus enabling an identification of these groups. In computing the second moment, account has been taken of both intra- and intermolecular dipole-dipole interactions. It is shown that the introduction of substituents into some ferrocene rings affects the magnitude of the re-orientation energy for both the substituted and unsubstituted rings. The change of the re-orientation energy of the substituted and unsubstituted rings in substituted ferrocenes with the structure and electronic properties of the substituents is discussed. 相似文献
