On Observability of Signal Over Background / Bityukov, S I (Serpukhov, IHEP) ; Krasnikov, N V (Moscow, INR)
Several criteria used by physicists to quantify the ratio of signal to background in planned experiments are compared. An equal probabilities test is proposed for the evaluation of the uncertainty in planned search experiments. [...]

Uncertainties and Discovery Potential in Planned Experiments / Bityukov, S I (Serpukhov, IHEP) ; Krasnikov, N V (Moscow, INR)
We describe a method for estimation of the discovery potential on new physics in planned experiments. The effective significance of signal for given probability of observation is proposed for planned experiments instead of the usual significances S_1 = n_s/sqrt{n_b} and S_2 = n_s/sqrt{n_s+n_b}, where n_s and n_b are the average numbers of signal and background events.

Statistically dual distributions in statistical inference / Bityukov, S I (Serpukhov, IHEP) ; Smirnova, V V (Serpukhov, IHEP) ; Krasnikov, N V (Moscow, INR) ; Taperechkina, V A (Unlisted, RU)
The estimation of a parameter of a model by the measurement of a random variable whose distribution depends on this parameter is one of the main tasks of statistics. In this paper the notion of the statistically dual distributions is introduced. [...]

The probability of making a correct decision in hypotheses testing as estimator of quality of planned experiments / Bityukov, S I ; Krasnikov, N V
In the report the approach to estimation of quality of planned experiments is considered. This approach is based on the analysis of uncertainty, which will take place under the future hypotheses testing about the existence of a new phenomenon in Nature. [...]

The Measurement of the 4-jet Cross Section at LHC as a Probe of New Physics / Bityukov, S I (Serpukhov, IHEP) ; Krasnikov, Nikolai (INR, Moscow, Russia)
We investigate the possibility to look for new physics by the measurement of the 4-jet cross section at the LHC. In particular, we consider a model with scalar colour octet and a supersymmetric model with R-parity violation. [...]

The LHC (CMS) Discovery Potential for Models with Effective Supersymmetry and Nonuniversal Gaugino Masses. / Bityukov, S I (CERN ; Serpukhov, IHEP) ; Krasnikov, Nikolai (CERN ; INR, Moscow, Russia)
We investigate squark and gluino pair production at LHC (CMS) with subsequent decays into quarks, leptons and LSP in models with effective supersymmetry where third generation of squarks is relatively light while the first two generations of squarks are heavy. We consider the general case of nonuniversal gaugino masses. [...]

Gaugino pair production at LHC for the case of nonuniversal gaugino masses / Bityukov, S I (Moscow, INR) ; Krasnikov, N V
We investigate \chi^{+/-}_1 \chi^0_2 pair production at LHC (CMS) with subsequent decays into leptons for the case of nonuniversal gaugino masses. Visibility of signal by an excess over SM background in 3 leptons + no jet + E^{miss}_T events depends rather strongly on the relation between LSP mass investigation of squark and gluino production at LHC for the case of nonuniversal gaugino masses..

Using the $e^{\pm}\mu^{\mp} + E_{T}^{miss}$ Signature in the Search for Supersymmetry and Lepton Flavour Violation in Neutralino Decays / Andreev, Yu.M. (Moscow, INR) ; Bityukov, S.I. (Serpukhov, IHEP) ; Krasnikov, N.V. (Moscow, INR) ; Toropin, A.N. (Moscow, INR)
The LHC (CMS) discovery potential of the $e^{\pm}\mu^{\mp} + E^{miss}_T$ signature in the search for supersymmetry and lepton flavour violation in neutralino decays is studied. A detailed study is done for the CMS test points LM1-LM9. [...]
