ABSTRACT: In the experimental search for the light Higgs boson, we considered a new signature of the charged Higgs boson, pp → H±h → W±hh, which is almost background free as the promising to study of supersymmetry at the LHC with both energy of 13 TeV and 14 TeV. In the framework of the MSSM model we used the latest parameter space, which is consistent with both the experimental constraints obtained at the LHC and theoretical calculations. In the surviving regions with the help of Pythia 8.3 and Feynhiggs programs it was found that production cross sections, σ(pp → H±h), and Branching Ratios, BR(H± → W±h), are the largest at Benchmark Points 4 and 14 correspondingly. The corresponding mass distributions and kinematical cuts of the lightest, h, and charged Higgs boson, H±, were obtained..

Keywords: Higgs boson; MSSM model.

ABSTRACT: This article gives a method to find the properties of a Si (100) MOS device, given the transverse and longitudinal electron effective masses in the semiconductor and its bandgap, without fabricating the MOS device. The study also highlights a significant scientific concept of physics that the electron effective masses in semiconductors and insulators are not only related to the mobility through drift velocity, but are also related to the intrinsic Fermi energy below the conduction band of the semiconductor through the relation dE/E equals dm/m, where dE is the differential kinetic energy of the moving electron, E is the semiconductor bandgap, dm is the effective mass of the electron and m is the free electron mass

ABSTRACT: Three different physical quantities: Nature Quantities (such as a piece of space or time); Associated Quantities (such as the dimension and duration of an object or event); and Measured Quantities (such as X number of minutes and Y number of meters) are clearly defined and compared. Also, arithmetic operations including addition, subtraction, multiplication and division applied on Associated Quantities (such as M/S and M1M2/R2) and Measured Quantities (such as m/s and Kgm/s2) are interpreted. Furthermore, commutativity, associativity and distributivity of Associated Quantities and Measured Quantities are derived.

ABSTRACT: Physical constants and their arithmetic operations are defined, and commutativity, associativity and distributivity of the operations are derived. Equations of physical laws are interpreted by the equality between two associated quantities of induced properties of the same interactive object or event caused by two objects or events. Compared to mathematical constants which contain only real numbers and remain always unchanged, physical constants however contain additional unit quantities with arithmetic operations and they are dependent on gravitational field and aging of the universe.

ABSTRACT: ZnS nanoparticles are successfully synthesized via the co-precipitation method. The powder XRD confirmed the cubic crystal structure for all the samples. TEM image indicated spherical shape with it size in the range of 10 nm -20 nm. The HRTEM shows nano sized nature of the particles. The FT-IR spectrum indicates the presence of, N-H rocking and stretching, C=C group, C=O carbonyl group (keton group), and C–N vibration, C=O stretching in L-arginine doped samples. The thermogram suggested that decomposition of the samples occurs by three stages and almost equal amount of final residue at the final stage due to least amount of amino acid entered in to parent structure of ZnS. The EDAX analysis is done confirm the presence of L-arginine in ZnS nanoparticles.

Keywords: ZnS, L-arginine doped ZnS, nano particles, powder XRD, FT-IR, TEM, TGA and EDAX.

ABSTRACT: Undoped Bismuth trioxides (Bi2O3) thin films were prepared using the spray pyrolysis technique at 350°C on glass substrates. Cu/ Bi2O3 structures were obtained when deposited by means of the thermal evaporation of 10 nm of Cu metal onto Bi2O3 sprayed thin films and then treated at 500°C using a thermal programmable oven during 1h. First, obtained thin films of Cu doped Bi2O3 as well as undoped ones were characterized using X-ray diffraction (XRD), Raman spectroscopy, ultraviolet–visible absorbance spectroscopy (UV–vis) and the impedance spectroscopy. According to X-ray diffraction results undoped samples have two peaks related to cubic phase of Bismuth trioxide (Bi2O3) while the doped ones crystallize in the same phase with a Copper oxide (CuO) as minority phase.......
