Search for a light pseudoscalar Higgs boson produced in association with bottom quarks in pp collisions at sqrt(s)=8 TeV

Abstract: A search for a light pseudoscalar Higgs boson (A) produced in association with bottom quarks and decaying into a muon pair is reported. The search uses 19.7 inverse femtobarns of proton-proton collisions at a center-of-mass energy of 8 TeV, collected by the CMS experiment. No signal is observed in the dimuon mass range from 25 to 60 GeV. Upper limits on the cross section times branching fraction, sigma(pp to b bbar A) B(A to mu mu), are set.

Rheological characterization of Nanocomposite modified asphalt binder

Abstract: Increase in traffic loading on pavement structures has necessitated use of asphalt with high durability, resistant to permanent deformation and most significantly higher service life of pavements. Rutting at high temperature and fatigue cracking under repeated loading are the major structural distresses in asphalt pavements. In some regions the base binder fails to serve the required purpose and their properties need to be modified by adding suitable materials. Nano-materials have unique properties which have led to increased interest of its use as an additive to asphalt binder. Therefore, in this study the effects of Nano titanium dioxide (TiO2) used as second modifier to modify polymer modified asphalt (PMA) binder have been investigated. Frequency sweep, temperature sweep, Linear Amplitude Sweep (LAS) and Multiple Stress Creep Recovery (MSCR) tests were carried out. The results showed that addition of Nano-TiO2 in PMA results in overall enhancement of properties of asphalt binder.

Estimation of strength and wear properties of Mg/SiC nanocomposite fabricated through FSP route

Abstract: The present paper discusses the effects of friction stir processing (FSP) on properties of Mg–SiC nanocomposite. The magnesium-based RZ5 alloy, widely used for aerospace applications, was used in the present investigation as the matrix for the purpose of nanocomposite fabrication. SiC powders of nanosize were reinforced into the RZ5 matrix by FSP with varying process parameters. The process was studied with respect to the effects of parameters such as rotational speed, traverse rate, and number of passes on the nanocomposite. With appropriate parameters, uniform distribution of nanoSiC reinforcements was accomplished in the metal matrix. The abrasive wear property of the Mg–SiC nanocomposite was verified with respect to the FSP process parameters. A mathematical model was also developed to predict the strength and abrasive wear characteristics of the nanocomposite with respect to the FSP parameters.
