Search for a massive resonance decaying into a Higgs boson and a W or Z boson in hadronic final states in proton-proton collisions at √s = 8 TeV

Abstract: A search for a massive resonance decaying into a standard- model-like Higgs boson (H) and a W or Z boson is reported. The analysis is performed on a data sample corresponding to an integrated luminosity of 19.7 inverse femtobarns, collected in proton-proton collisions at a centre-of-mass energy of 8 TeV with the CMS detector at the LHC. Signal events, in which the decay products of Higgs, W, or Z bosons at high Lorentz boost are contained within single reconstructed jets, are identified using jet substructure techniques, including the tagging of b hadrons. This is the first search for heavy resonances decaying into HW or HZ resulting in an all-jet final state, as well as the first application of jet substructure techniques to identify H to WW* to 4q decays at high Lorentz boost. No significant signal is observed and limits are set at 95% confidence level on the production cross section of W' and Z' in a model with mass-degenerate charged and neutral spin-1 resonances. Resonance masses are excluded for W' in the interval [1.0, 1.6] TeV, for Z' in the intervals [1.0, 1.1] and [1.3, 1.5] TeV, and for mass-degenerate W' and Z' in the interval [1.0, 1.7] TeV.

Simultaneous Adsorption of H2S and CO2 on Triamine-Grafted Pore-Expanded Mesoporous MCM-41 Silica

Abstract: The feasibility of using triamine-grafted pore-expanded mesoporous MCM-41 silica (TRI-PE-MCM-41) as a potential adsorbent for simultaneous removal of CO2 and H2S was investigated. Adsorption isotherms of CO2 and H2S were measured at different temperatures, whereas adsorption at low H2S concentrations from 700 to 10000 ppm with balance CO2 was studied at 298 K. It was found that both CO2 and H2S adsorb and the selectively toward H2S versus CO2 decreases at an increasing H2S concentration. Because TRI-PE-MCM-41 hardly adsorbs any of the common gases, such as CH4, H2, N2, O2, and CO, it was inferred that this material may be suitable for the purification of a variety of gas streams containing CO2 and H2S. These findings lay the ground for the development of a single-stage process for the removal of CO2 and H2S from biogas, using amine-supported PE-MCM-41.
