Heavy states of hadron string as weak interacting massive particles for Dark Matter
Massive states (of order 10 Gev and more) of hadron string (with scale 1 Gev) can have very small coupling constants with usual baryons of the Universe. Corresponding mean times for them are found to be order and even more than the age of the Universe. They are proposed as possible candidates for weak interacting massive particles (WIMP) of Dark Matter.

title: Fermion dominated composite superstring model and unified description of hadron and lepton degrees of freedom in it
abstract: New string dynamics is formulated on the basis of the extended set of supergauge constraints including not only supergauge Virasoro conditions but also nilpotent supercurrent constraints . This approach arises from a natural generalization of the classical operator many-string vertices. The formulation of this model leads to three two-dimensional surfaces for description of hadron strings. It gives some dynamical generalization of Chan-Paton factor for string amplitudes in terms of operator vertices. Supersymmetry on the 2-d world surface is present but ten-dimensional supersymmetry is absent. In this approach two-dimensional fermion string fields make it possible to give a unified description of hadron and lepton degrees of freedom and of its dynamics. This model allows to solve the problem of elimination of the most part of parity twins in the baryon spectrum. One-loop (and many-loops perhaps) amplitudes in this model are finite due to the extended set of supergauge constraints and to the significant excess of the total number of fermion two-dimensional fields over the number of boson 2-d fields.

abstract: The primary mechanism for the production of high-energy muons (E/sub / > 5 TeV) in extensive air showers from primary el rays is the production of muon pairs by shower photons in the field of a nucleus.

title: Quasi-stable states in the physical spectrum of the Neveu-Schwarz dual model
abstract: A certain class of states, comprising most of the spectrum for large mass M, is distinguished in the spectum of physical states predicted by the Neveu-Schwarz dual model with intercepts ..cap alpha../sub rho/(0) =1 and ..cap alpha../sub ..pi../(0) =1/2. The massive particles with large spins in this class are quasi-stable. Their couplings with all the other states are of order M/sup -1/ in comparison with the ordinary vertices. For the critical dimensions D=10 these states coincide with the zero-norm spurions. For the anomalous dimensions D=9 some of the quasi-stable states become new zero-norm spurion states.

title: ZEPLIN‐II limits on WIMP‐nucelon interactions
abstract: ZEPLIN II is a two‐phase xenon detector designed to detect dark matter in the form of Weakly Interacting Massive Particles (WIMPs). Following the first 31‐day underground run in Boulby Mine, UK, the collaboration published dark matter limits in January 2007; the first such limits using two‐phase xenon technology. We outline the key detector design, performance and results here.

title: Search for the lepton-flavor violating decays $B^0_s \rightarrow e^{\pm}\mu^{\mp}$ and $B^0 \rightarrow e^{\pm} \mu^{\mp}$
abstract: A search for the lepton-flavour violating decays $B^0_s \to e^{\pm} \mu^{\mp}$ and $B^0 \to e^{\pm} \mu^{\mp}$ is performed with a data sample, corresponding to an integrated luminosity of 1.0 fb$^{-1}$ of $pp$ collisions at $\sqrt{s} = 7$ TeV, collected by the LHCb experiment. The observed number of $B^0_s \to e^{\pm} \mu^{\mp}$ and $B^0 \to e^{\pm} \mu^{\mp}$ candidates is consistent with background expectations. Upper limits on the branching fractions of both decays are determined to be $BR(B^0_s \to e^{\pm} \mu^{\mp}) 107$ TeV/c$^2$ and $M_{\rm LQ} (B^0 \to e^{\pm} \mu^{\mp}) > 126$ TeV/c$^2$ at 95% C.L., and are a factor of two higher than the previous bounds.

title: Combined limits on WIMPs from the CDMS and EDELWEISS experiments
abstract: The CDMS and EDELWEISS collaborations have combined the results of their direct searches for dark matter using cryogenic germanium detectors. The total data set represents 614  kg·days equivalent exposure. A straightforward method of combination was chosen for its simplicity before data were exchanged between experiments. The results are interpreted in terms of limits on spin-independent weakly interacting, massive particle (WIMP)-nucleon cross section. For a WIMP mass of 90  GeV/c^2, where this analysis is most sensitive, a cross section of 3.3×10^(-44)  cm^2 is excluded at 90% C.L. At higher WIMP masses, the combination improves the individual limits, by a factor 1.6 above 700  GeV/c^2. Alternative methods of combining the data provide stronger constraints for some ranges of WIMP masses and weaker constraints for others.

title: Observation of associated production of a Z boson with a D meson in the forward region
abstract: A bstractA search for associated production of a Z boson with an open charm meson is presented using a data sample, corresponding to an integrated luminosity of 1.0 fb−1 of proton-proton collisions at a centre-of-mass energy of 7TeV, collected by the LHCb experiment. Seven candidate events for associated production of a Z boson with a D0 meson and four candidate events for a Z boson with a D+ meson are observed with a combined significance of 5.1 standard deviations. The production cross-sections in the forward region are measured to be
$ \begin{array}{*{20}{c}} {{\upsigma_{{\mathrm{Z}\to {\upmu^{+}}}}}{{{_{{{\upmu^{-}}}}}}_{{,{{\mathrm{D}}^0}}}}=2.50\pm 1.12\pm } \\ {{\upsigma_{{\mathrm{Z}\to {\upmu^{+}}}}}{{{_{{{\upmu^{-}}}}}}_{{,{{\mathrm{D}}^{+}}}}}=0.44\pm 0.23\pm 0.03\ \mathrm{pb},} \\ \end{array} $
where the first uncertainty is statistical and the second systematic.
