In vitro experiment was carried out to see the effect of saw dusts of Pinus kesiya, Shorea robusta, and Callicarpa arborea on Trichoderma harzianum, isolate TH-13 mass production, along with its biotization effect on Capsicum chinensis Jacq. "Bhut Jolokia." Early mycelium initiation (2 days) occurred in S. robusta followed by P. kesiya and C. arborea (3.5 days). The sporulation was observed ear...
A study of the ν̄-jet mass spectrum in e+p → ν̄X events at center-of-mass energy 300 GeV has been performed with the ZEUS detector at HERA using an integrated luminosity of 47.7pb. The mass spectrum is in good agreement with that expected from Standard Model processes over the ν̄-jet mass range studied. No significant excess attributable to the decay of a narrow resonance is observed. By using bot...
In the CP–invariant supersymmetric theories, the steep S–wave (slow P–wave) rise of the cross section for any non–diagonal neutralino pair production in e+e− annihilation, e+e− → χ̃i χ̃ 0 j (i 6= j), near threshold is accompanied by the slow P–wave (steep S–wave) decrease of the fermion invariant mass distribution of the 3–body neutralino decay, χ̃i → χ̃ 0 j f f̄ (f = l or q), near the end point. Th...
We study high–p T Higgs boson production at hadron colliders to order O(α s G 3 F) in hadron collisions. In particular, we investigate the process g + q/q → q/q + H, where q = u, d, c, s, or b, for the LHC (a √ s =14 TeV, proton–proton collider). Our results are compared to the O(α 3 s G F) calculation. The associated production of a high–p T Higgs boson with a b–quark or anti–quark is comparab...
Cross sections are presented for the inclusive production of charged particles measured in electron-proton collisions at low Q 2 with the H1 detector at HERA. The transverse momentum distribution extends up to 8 GeV/c. Its shape is found to be harder than that observed in pp collisions at comparable centre-of-mass energies p s p p s pp 200 GeV, and also harder than in p collisions at lower ener...
The existence of a new massive charged gauge boson, known as W’, is proposed by many new physics scenarios. When W’ decays to tb, the final state is very similar to the final state of the s-channel single top production, where W boson is the off-shell mediator to produce the top and bottom quarks. If W’ exists, it can affect the cross section of the SM s-channel single top production, so measur...
The OPAL collaboration has searched for the associated production of massive particles in 4-jet nal states at e + e ? center-of-mass energies of p s = 130{136 GeV at LEP. In this note we present preliminary upper limits on the production cross section of narrow states X and Y in the process
From the pion production rates n π /A part and the pion charge ratios R π = n π − /n π + and S π = n π 0 /(n π − + n π +), measured in p + a and A + A reactions, it is concluded that the mass of the ∆(1232) resonance is reduced in dense nuclear matter. This conclusion is supported by the ∆(1232) mass distribution extracted from correlated (p,π ±) pairs and the π ± transverse momentum distributi...
