A search for particles with the same mass and couplings as those of the standard model Higgs boson but different spin and parity quantum numbers is presented. We test two specific alternative Higgs boson hypotheses: a pseudoscalar Higgs boson with spin-parity J^{P}=0^{-} and a gravitonlike Higgs boson with J^{P}=2^{+}, assuming for both a mass of 125 GeV/c^{2}. We search for these exotic state...
The aim of this study was to determine the inhibitory effects of feed ingredients on protease activities of Argyrosomus regius larvae using in vitro techniques. A. regius larvae fed on a commercial feeding procedure were sampled thirteen times, during the sampling period (from 3 to 32 days after hatching (DAH)). The differences observed in protease activities of meagre larvae during the samplin...

The cross section for inclusive prompt photon production with polarized hadron beams is calculated at order αα 2 s using the phase space slicing or analytic/Monte Carlo method. Isolation cuts are placed on the photon and the results are compared to a previous fully analytic calculation. Numerical results for the isolated cross section are presented for for p p → γ + X at RHIC center-of-mass ene...
We report measurements of single- and double-spin asymmetries for W^{±} and Z/γ^{*} boson production in longitudinally polarized p+p collisions at sqrt[s]=510 GeV by the STAR experiment at RHIC. The asymmetries for W^{±} were measured as a function of the decay lepton pseudorapidity, which provides a theoretically clean probe of the proton's polarized quark distributions at the scale of the W ...
We study the anomalous $$W^+W^-\gamma $$ couplings in performing production of W-pair through process $$e^- p\,\rightarrow \,e^-\gamma ^*\gamma ^* \,e^-W^+W^-p$$ at Large Hadron electron Collider (LHeC) and Future Circular Collider-hadron (FCC-he). examine pure hadronic, semi-leptonic leptonic decay channels produced W-pair. assume center-of-mass energies $$\sqrt{s}=1.30$$ 1.98 TeV integrated l...
A search for excited neutrinos, the analysis of multi-lepton final states, a search for doubly charged Higgs production and a general search for high-P T phenomena at HERA are reported. The searches use data samples of e ± p collisions with a centre-of-mass energy √ s = 320 GeV collected by the H1 and ZEUS experiments at HERA in the years 1994-2005 with integrated luminosities up to L = 296 pb ...
I review recent progress on bottom-quark fragmentation in e + e − annihilation, top-quark decay and H → b ¯ b processes. I discuss the implementation of collinear and soft resummation, and the inclusion of non-perturbative information taken from LEP and SLD data. Heavy-quark physics is currently one of the major fields of investigation in experimental and theoretical particle physics. In order ...
Searches for standard model Higgs boson production in p¯ p collisions at √ s = 1.96 TeV are carried out for Higgs boson masses (mH) in the range 100 ≤ mH ≤ 200 GeV/c 2. The contributing production processes include gluon-gluon fusion (gg →H), associated production (q ¯ q →V H) and vector boson fusion (q ¯ q →q ¯ qH). Analyses are conducted over an array of distinct final states with integrated ...
