Description
This is the second exploratory workshop aiming at studying in detail the opportunity and feasibility of a fixed-target experiment using the LHC beams extracted by a bent crystal.

A special emphasis will be put on studies related to Strong Interactions. Complementarity with existing experiments at the LHC, at SPS, at CEBAF, at Fermilab and RHIC will also be the cornerstone of the discussions

        Quark tensor and axial charges within the Schwinger-Dyson formalism (30'+5')
        We calculate the tensor and axial charges of the quark in the QCD-like theory in the Landau gauge by solving the Schwinger-Dyson equation. It is found that the dressed tensor and axial charges of the quark are significantly suppressed against the bare quark contribution, and the result is quite consistent with the analyses in the collinear factorization approach and the lattice QCD. We show that the suppression of the quark tensor and axial charges is due to the superposition of the spin flip of the quark arising from the successive emission of gluons dressing the tensor and axial vertices.

        Production of hypernuclei from excited nuclear residues in relativistic ion collisions: New opportunities for AFTER@LHC (30'+5')
        Investigation of hypernuclei is a rapidly progressing field of nuclear physics, since they open both opportunities to improve methods of traditional nuclear studies and new horizons for studying particle physics and nuclear astrophysics. Within dynamical and statistical theories we study the main regularities in the production of hypernuclei emerging from the projectile and target residues in relativistic ion collisions. This process will allow to study the mechanisms of peripheral collisions and the properties of hyper-matter of low temperatures, including hyperon-hyperon interactions at low energies. We demonstrate that the yields of hypernuclei increase considerably at beam energies above the energy threshold for Lambda hyperons, followed by a saturation for yields of hypernuclei with increasing the beam energy up to few TeV (LHC energies) [1]. These hypernuclei have a broad distribution in masses and isospin. They can even reach beyond the neutron and proton drip-lines since they are stable with respect to nucleon emission [2]. Weak decay of such hypernuclei may lead to formation of normal nuclei beyond the drip-lines also, thus providing a unique chance for reaching island of stability on the nuclear chart. The production of specific hypernuclei depend strongly on the isotopic composition of the projectile, therefore, it will be possible to obtain exotic hypernuclei that may be difficult to reach in traditional hypernuclear experiments [1]. The perspectives of hypernuclear studies involving these novel processes at the present accelerators are discussed. [1] A.S. Botvina, K.K. Gudima, and J. Pochodzalla, Phys. Rev. C88, 054605 (2013).
