New heavy gauge bosons belonging to an extended (in relation to the Standard Model) gauge sector are present in Grand Unified Theories, as well as in a number of models aimed at solving the hierarchy problem—in particular, in the technicolor model and in some versions of multidimensional field theories (for example, in the Little Higgs model). The LHC potential for seeking new neutral gauge bosons in decays to two muons is studied.

A brief survey of the present-day status of the problem of multidimensional-black-hole production at accelerators according to models featuring large extra dimensions is given. The respective production cross section and the Hawking temperature and decay rate are estimated versus model parameters. Possible flaws and assumptions whose accurate inclusion can reduce significantly the probability of blackhole production at accelerators in relation to earlier optimistic estimates are also discussed.

A survey of the results of the Compact Muon Solenoid (CMS) experiment that concern searches for massive Kaluza-Klein graviton excitations and microscopic black holes, quantum black holes, and string balls within models of low-energy multidimensional gravity is presented on behalf of the CMS Collaboration. The analysis in question is performed on the basis of a complete sample of data accumulated for proton-proton collisions at the c.m. energies of 7 and 8 TeV at the Large Hadron Collider (LHC) over the period spanning 2010 and 2012.

If the fundamental scale of multidimensional gravity is about one or several TeV units, microscopic black holes or objects referred to as string balls may be produced at the LHC. The most recent results obtained by the CMS Collaboration at the LHC from searches for such signals at the c.m. protoninteraction energy of 7 TeV and for an integrated luminosity of 4.7 fb−1. Lower limits on the masses of objects of strongly acting gravity were set in the parameter region accessible to tests at the present time. Prospects for further research in this field are discussed.

AbstractThe effect of parton shadowing on the distributions of global observables (total transverse energy ET and charged-particle multiplicity nch) is investigated on the basis of the HIJING model of nucleus-nucleus interactions. It is shown that, for the interaction of lead nuclei at
