Nuclotron based Ion Collider fAcility (NICA) project is in progress at the Joint Institute for Nuclear Research and will start experiments with heavy ions. In the context of the NICA Hadronic Physics programme double polarized pp-, dd-and pd-collisions even at lower energies of √ sNN = 3.4 − 10 GeV, which will be accessible already at the initial stage of experiments,are essential tools for precise understanding the spin dependence of the nucleon-nucleon strong interactions, in both elastic and deep-inelastic regimes. A special interest is interaction in few baryon systems at double strangeness, charm and beauty thresholds.For instance, polarized large-angle elastic pp and pn scattering near the charm threshold allows one to get an access to properties of possible exotic multiquark states and their relation to the states recently observed at LHCb.Large angle scattering of protons and deuterons on the deuteron contains unique information on the short-range structure of the deuteron, its non-nucleonic degrees of freedom and also on color transparency phenomenon. Furthermore, double polarized proton-deuteron scattering offer a possibility to test the Standard Model through the search for time-invariance (or CP-invariance under CPT symmetry) violation and parity-violation in single-polarized scattering. This paper contains suggestions for experiments with usage of the Spin Physics Detector (SPD) and discusses perspectives of the first stage of the SPD Programme. This includes experiments with non-polarized beams too as well as collisions like 12 С-12 С and 40 Сa-40 Ca.9 Multiquark correlations and exotic hadron state production 9 9.1 Multiquark correlations and exotic state production at SPD NICA . . . .

Dark matter is an important component of the Standard model of cosmology but its nature is still unknown. One of the most common explanations is that dark matter consists of Weakly Interacting Massive Particles (WIMPs), supposed to be cold thermal relics of the Big Bang and to build up the galactic dark halos. Indirect search of dark matter could be performed via the study of an anomalous antiproton component in cosmic rays originating from possible annihilation of dark matter pairs in the galactic halo, on top of the standard astrophysical production. The measurements performed by the AMS-02 and PAMELA spectrometers have shown that limited knowledge of antiproton-production cross sections in pp, pD, pHe and HeHe collisions is one of the main uncertainties of background subtraction. The planned SPD experiment at the NICA collider could provide a precision measurement of antiproton yield in wide kinematic range in pp and pD collisions at the energy scale from the threshold to √ s = 26 GeV/c.

In a hadron collider like the Large Hadron Collider (LHC), the dimuon channel provides an ideal tool for the discovery of many predicted particles from Beyond Standard Model (BSM) theories such as high mass resonant, or non-resonant states. The high mass resonances like Z' and the high mass non-resonant like contact interactions or extra dimensions should appear in the high mass tail of dimuon distributions. The Drell-Yan process is the main source of high mass opposite sign muon pairs in the Standard Model (SM) which act as the irreducible background of signals of the above mentioned BSM models in proton-proton collisions. Therefore, it is important to study with the highest possible accuracy the Drell-Yan process.In this paper, the expectations of the Drell-Yan process in the dimuon channel at next-to-next-to-leading order in QCD and next-to-leading order in the electroweak corrections are studied in detail. In the present study, a typical generic detector acceptance such as CMS or ATLAS at the LHC at center of mass energy 14 TeV is considered. At the end of this study, estimates of the expected backgrounds for new physics searches in the dimuon final states are given.

The present study is concerned with the Randall-Sundrum (RS) model that predicts the existence of narrow resonances that appear in the di-lipton invariant mass distribution in proton-proton collisions. This gives the final state with di-muon having large invariant mass from the decay of the RS1 graviton. A Large Hadron Collider (LHC) feasibility study for five-sigma discovery at 14 TeV was performed. The Kaluza-Klein graviton (G KK) production cross sections as a function of the graviton mass are presented and the limits on cross sections times branching ratio into muons to observe a 5 σ signal are presented. Our estimates are based on integrated luminosity of 100 fb-1 and 1000 fb-1. The conclusion of our study is that the LHC can test the RS1 graviton existence if it is already existing with masses up to 2.6 TeV/c 2 (3 TeV/c 2) at a luminosity of 100 fb-1 (1000 fb-1), when the parameter c (model parameter) is equal to 0.01. With the optimistic scenario, at c equal to 0.1, the G KK could be discovered if it is existing with mass up to 5 TeV/c 2 with 100 fb-1 and mass up to 6.5 TeV/c 2 with 1000 fb-1 .
