We investigate the possibility to look for new physics by the measurement of the 4-jet cross section at LHC and FNAL. In particular, we consider the model with scalar colour octet and the…

We study a possibility to detect sleptons at post-WMAP benchmark points at LHC(CMS). We find that at L tot = 30 fb − 1 it would be possible to detect sleptons at points A, B, C, D, G. We also…

For Poisson distribution Pois(n, λ) with λ ≫ 1, n ≫ 1 we propose to determine significance as S = nobs − λ √ λ . The significance S coincides up to sign with often used significance. For experiments…

Several criteria used by physicist to quantify the ratio of signal to background are compared .The approach for taking into account the uncertainty in estimations of signal and background is proposed.
