Primordial Black Holes from Spatially Varying Cosmological Constant Induced by Field Fluctuations in Extra Dimensions / Popov, Arkady A. (Kazan State U.) ; Rubin, Sergey G. (Kazan State U. ; Moscow Phys. Eng. Inst.) ; Sakharov, Alexander S. (Manhattan Coll., Riverdale ; CERN)
The origin and evolution of supermassive black holes (SMBHs) in our universe have sparked controversy. In this study, we explore the hypothesis that some of these black holes may have seeded from the direct collapse of dark energy domains with density significantly higher than the surrounding regions. [...]

IDEA (Innovative Detector for Electron–positron Accelerators) is a detector concept designed for a future leptonic collider operating as a Higgs factory. It is based on innovative detector technologies developed over years of R&D.; In September 2018, prototypes of the proposed sub-detectors have been tested for the first time on a beam line at CERN.

Searches for anomalous coupling in top-quark interaction with the $W $boson and $b$ quark, along with searches for quark-flavor-changing neutral currents, in an analysis of data from the CMS Experiment / Boos, E E (SINP, Moscow) ; Bunichev, V E (SINP, Moscow) ; Vorotnikov, G A (SINP, Moscow) ; Dudko, L V (SINP, Moscow) ; Myagkov, I A (SINP, Moscow) ; Perfilov, M A (SINP, Moscow) ; Popov, A A (SINP, Moscow) ; Tsirova, N A (SINP, Moscow) ; Shvetsov, I A (Karlsruhe, Forschungszentrum) /CMS
The results of searches for effects beyond the Standard Model in processes of single top-quark production in the CMS experiment are presented. Anomalous contributions of the vector and magnetic types in top-quark interaction with the W boson and b quark and quark-flavor-changing neutral currents in top-quark interaction with the c or u quark via gluon exchange were studied.

Double spin asymmetry in exclusive $\rho^0$ muoproduction at COMPASS / COMPASS Collaboration
The longitudinal double spin asymmetry A_1^rho for exclusive leptoproduction of rho^0 mesons, mu + N -> mu + N + rho, is studied using the COMPASS 2002 and 2003 data. The measured reaction is incoherent exclusive rho^0 production on polarised deuterons. [...]

The COMPASS Experiment at CERN / COMPASS Collaboration
The COMPASS experiment makes use of the CERN SPS high-intensitymuon and hadron beams for the investigation of the nucleon spin structure and the spectroscopy of hadrons. One or more outgoing particles are detected in coincidence with the incoming muon or hadron. [...]

Spin asymmetry $A^d_1$ and the spin-dependent structure function $g^d_1$ of the deuteron at low values of $x$ and $Q^2$ / COMPASS Collaboration
We present a precise measurement of the deuteron longitudinal spin asymmetry A_1^d and of the deuteron spin-dependent structure function g_1^d at Q^2 < 1 GeV^2 and 4*10^-5 < x < 2.5*10^-2 based on the data collected by the COMPASS experiment at CERN during the years 2002 and 2003. The statistical precision is tenfold better than that of the previous measurement in this region. [...]

A new measurement of the Collins and Sivers asymmetries on a transversely polarised deuteron target / COMPASS Collaboration
New high precision measurements of the Collins and Sivers asymmetries of charged hadrons produced in deep-inelastic scattering of muons on a transversely polarised 6LiD target are presented. The data were taken in 2003 and 2004 with the COMPASS spectrometer using the muon beam of the CERN SPS at 160 GeV/c [...]

The Deuteron Spin-dependent Structure Function $g^{d}_1$ and its First Moment / COMPASS Collaboration
We present a measurement of the deuteron spin-dependent structure function g^d_1 based on the data collected by the COMPASS experiment at CERN during the years 2002-2004. The data provide an accurate evaluation for \Gamma^d_1, the first moment of g^d_1(x), and for the matrix element of the singlet axial current, a_0. [...]

Gluon polarization in the nucleon from quasi-real photoproduction of high-pT hadron pairs / COMPASS Collaboration
We present a determination of the gluon polarization Delta G/G in the nucleon, based on the helicity asymmetry of quasi-real photoproduction events, Q^2<1(GeV/c)^2, with a pair of large transverse-momentum hadrons in the final state. The data were obtained by the COMPASS experiment at CERN using a 160 GeV polarized muon beam scattered on a polarized 6-LiD target. [...]

Search for the $\phi (1860)$ Pentaquark at COMPASS / COMPASS Collaboration
Narrow Xi-pi+- and Xi-bar+pi+- resonances produced by quasi-real photons have been searched for by the COMPASS experiment at CERN. The study was stimulated by the recent observation of an exotic baryonic state decaying into Xi-pi-, at a mass of 1862 MeV, interpreted as a pentaquark. [...]
