The importance of application of the kinematical constraint on the evolution of unintegrated parton density functions in the BFKL formalism was studied in recent publications. In this talk we focus on the role of the kinematical constraint in the CCFM equation and its non-linear extension. We compare numerical results obtained by solving the CCFM equation and argue that kinematical constraint...

I will talk about collective aspects in theoretical description of ultra-relativistic p-A, d-A, and 3He-A (A is a heavy nucleus) collisions, where recent measurements have been carried out at RHIC and the LHC. I will also show predictions for 12C-A reactions, where the harmonic flow patterns are sensitive to the deformation of the 12C ground-state wave function, thus offering a new probe of...

The suppression of quarkonium production in high energy heavy-ion collisions relative to proton-proton collisions due to color screening was proposed as a signature of Quark-Gluon Plasma formation. Studies of quarkonium production in nuclear collisions can provide insight into the thermodynamic properties of the hot and dense medium created in relativistic heavy-ion collisions at RHIC....

The Dyson-Schwinger equation for the three-gluon vertex in Landau gauge
is solved without and with the quark triangle included. Hereby we
concentrate on quarks in the chiral limit and discuss implications of
our findings for the quark-gluon vertex.

The anomalous magnetic moment of the muon, defined as the fractional difference of its gyromagnetic ratio from the naive value of 2, has been measured with an impressive accuracy of 0.54 parts per million in experiment (BNL E821), thus providing one of the most stringent tests of the Standard Model. Intriguingly, the experimentally measured anomaly disagrees by around 3 standard deviations...

The effective actions of gauge bosons, fermions and scalars, which are obtained within the hard-loop approximation, are shown to have unique forms for a whole class of gauge theories including QED, scalar QED, super QED, pure Yang-Mills, QCD, super Yang-Mills. The universality occurs irrespective of a field content of each theory and of variety of specific interactions. Consequently, the...

We investigate four-quark systems consisting of two heavy anti-bottom
quarks and two light up/down quarks. To this end we solve a coupled
Schrödinger equation for the anti-bottom-anti-bottom separation using
potentials computed via lattice QCD in the limit of static anti-bottom
quarks. This coupled Schrödinger equation allows to incoporate effects
due to the heavy anti-bottom spins.

In the recently elaborated fully solvable mathematical problem to be concerned of a finding of an explicit form of the
pion scalar form factor the inaccurate experimental information in the elastic region

P-waves which satisfactorily describe the $\pi\pi$ scattering data [1].
In the construction we have utilized the uniformizing variable and
formulas for analytical continuation of the S-matrix elements to all
sheets of the Riemann surface but we did not fully include the constraint
on the crossing symmetry which is...

Despite the successes of the Standard Model, the QCD-based nature of the strong interaction is insufficiently understood. Charmonium spectroscopy is an ideal tool to provide insight into the non-perturbative dynamics of the strong force. It provides rigorous guidelines to various theoretical approaches, thereby, gaining insight into quark confinement and the formation of hadronic matter. The...

Solution of Schwinger-Dyson and Bethe-Salpeter Equations for excited and
ground state pions will be presented. The quark gap equation has been solved directly
in our Minkowski space-time and the solution, according to confinement, does not allow a free quark propagation. The Minkowski space solution for confining QCD
as will be shown, is not only numerically accessible, but also

This talk reviews some recent progress in making sense of confinement. The focus of the talk is on cousins of QCD, rather than QCD itself; these cousin theories have features lacking in QCD which facilitate the analysis. One critical feature of this sort is center symmetry, and the core of the talk is an exploration of the connection of center symmetry to confinement. One principal way to...

Lattice QCD simulations tend to become stuck in a single topological
sector at fine lattice spacing, or when using chirally symmetric
overlap quarks. In such cases computed observables differ from their
full QCD counterparts by finite volume corrections, which need to be
understood on a quantitative level. We discuss extensions of existing
relations from the literature between correlation...

Saturation of gluon distribution is a consequence of
non-linear evolution equations of QCD. Saturation implies
the existence of so called saturation momentum which is
gluon density per unit rapidity per transverse area. At
large energies for certain kinematical domains saturation
momentum is the only scale for physical processes. As
a consequence different observables exhibit so called...

Simulations with a finite chemical potential typically lead to a severe sign problem, prohibiting any standard Monte Carlo approach. For simulations of QCD we use the complex Langevin method, for which we apply adaptive step-sizes and gauge cooling to ensure the convergence. We present preliminary results for heavy quark QCD and explore the application for two dynamical quarks.

Ultra-relativistic collisions of heavy ions allow studying strongly interacting matter at extreme energy densities and temperatures. Quantum-Chromodynamics predicts that at such conditions normal, hadronic matter turns into a plasma of deconfined quarks and gluons, which are the constituents of atomic nuclei. In cosmology, it is believed that matter in the early universe must have existed in...

We present the Born amplitudes for the pi eta photoproduction on the nucleon. These amplitudes and the corresponding partial wave amplitudes are essential for the description of the photoproduction of isovector resonances with masses below 2 GeV. Some of these resonances, in particular $a_0(980)$ and $a_0(1450)$ are believed to have a substantial mollecular admixture. These mollecular states...

Anisotropies of transverse expansion flow in ultrarelativistic nuclear collisions are nowadays precisely measured and potentially carry important information about the transport properties of hot deconfined matter. In order to extract this information reliably from data analysis one must take into account other effects which can cause flow anisotropies. Hard partons, produced copiously at the...

We compute dilepton production from the deconfined phase of the quark-gluon plasma using
leading-order (3+1)-dimensional anisotropic hydrodynamics. The anisotropic hydrodynamics equations employed describe the full spatiotemporal evolution of the transverse temperature, spheroidal momentum-space anisotropy parameter, and the associated three-dimensional collective flow of the matter. The...

Ultra-relativistic heavy-ion collisions are a window of opportunity to study QCD matter under extreme conditions of temperature and density, such as the quark-gluon plasma. Among the several possibilities, the study of jet quenching - generic name given to in-medium energy loss modifications of the parton branching - is a powerful tool to assess the properties of this new state of matter. The...

In this talk we present some of the heavy-ion results from CMS, restricting on anisotropic particle emission. Consistency between the results obtained using four-, six and eigth-particle correlation as well as the Lee-Yang zero method reveals a multi-particle nature of the long-range correlations observed in pPb collisions. By correlating an identified strange hadron ($K^{0}_{S}$ or...

I will review our current understanding of the phase diagram of two-color quark matter with emphasis on the comparison of model and lattice results.

In ultrarelativistic heavy-ion collisions nuclear matter is heated to a temperature exceeding that necessary to create a quark-gluon plasma (QGP). Traditionally, second order viscous hydrodynamics has been used to reproduce the soft collective flow of the QGP and hadronic spectra; however, due to rapid longitudinal expansion in the early stages of evolution, the system may possess substantial...
