Based on numerical simulations of 6 GeV electron propagation through bent crystals with various orientations relative to the incident particle direction, as well as different bending radii and crystal thicknesses, we performed a comparative analysis of the deflection efficiency in planar and axial crystal orientations. To identify the optimal bent crystal parameters for maximum electron...

The Higgs boson discovery raised new questions about the Standard Model's mysteries, particularly the existence of three matter generations with vastly different masses. New physics might be revealed through electron-positron collider experiments at specific energy levels, as the Standard Model serves as a foundation for examining nature across all scales .

One of the main goals of relativistic heavy-ion experiments in the GeV range is to explore the QCD phase diagram, particularly at high baryon chemical potential, where critical features may emerge. At very high energies, such as at the LHC, the matter created is extremely hot with low net baryon density, and lattice QCD indicates a smooth crossover from quark–gluon plasma to hadronic matter....

The production of gauge fields during inflation has a wide range of phenomenological implications. It can affect the background dynamics of inflation, modify the spectral properties of primordial scalar and tensor perturbations, and lead to the creation of charged particles through the Schwinger effect. The latter can significantly suppress the efficiency of gauge-field production during...

The hard processes with n = 0,1,2, and 3 outgoing partons are generated by MadGraph5_aMC@NLO at next-to-leading order of perturbative QCD. The parton events are re-weighted to determine uncertainties of the observables...

LIVE Electronic Painting is expected to be for imaging of various beauties of Nature evolving in time. As an approach to that action one can use lasers with tunable frequency as electronic sources of wide range colors, varying in real time. The created paintings will be imaged by means of sophisticated electronic devices (Timepix display, for instance).

A compact radiation-hard monitoring module based on metal foil detectors (MFDs) is being developed for the CBM experiment at FAIR/GSI (SIS-100) in fixed-target mode (Au+Au, 2–11 GeV/n). The baseline detector is a 5-mm-thick module built as a 54-mm square copper frame housing a 50 × 50 mm² foil sensor with two 1-mm-spaced HV electrodes and 50-μm foils mechanically fixed by 125-μm plastic...

The Compressed Baryonic Matter (CBM) experiment at FAIR is designed to explore the QCD phase diagram in the region of high baryon density and low temperature using high-intensity proton and heavy-ion beams. The unprecedented interaction rate, reaching up to 10 MHz, results in a severe radiation load on detector components, making continuous radiation monitoring a critical requirement for...

The discovery of the Higgs boson marked a triumph of the Standard Model, yet fundamental questions remain unanswered: what triggers the electroweak symmetry breaking, why does the Higgs have its observed mass, and are there additional scalar fields? These questions drive the search for an extended Higgs sector where the Next-to-Two-Higgs-Doublet Model (N2HDM) stands as a particularly...

We consider a fast charged particle scattering on parallel atomic planes in the eikonal approximation of quantum electrodynamics. The eikonal approximation was chosen because it both accounts for quantum nature of the incident particle and has a wider region of applicability compared to the frequently used Born approximation. Based on Glauber's approach, we continued our previous works and...
