Electroweak effects in $e^+ e^- \to Z H$ process
[arXiv:2105.11708]
 GO
Electroweak radiative corrections to the cross section of the process $e^+ e^- \to Z H$ are considered. The complete one-loop electroweak radiative corrections are evaluated with the help of the SANC system. [...]

Rise and fall of laser-intensity effects in spectrally resolved Compton process
[arXiv:2105.11758]
 GO
The spectrally resolved differential cross section of Compton scattering, $d \sigma / d \omega' \vert_{\omega' = const}$, rises from small towards larger laser intensity parameter $\xi$, reaches a maximum, and falls towards the asymptotic strong-field region. Expressed by invariant quantities: $d \sigma /du \vert_{u = const}$ rises from small towards larger values of $\xi$, reaches a maximum at $\xi_{max} = \frac49 {\cal K} u m^2 / k \cdot p$, ${\cal K} = {\cal O} (1)$, and falls at $\xi > \xi_{max}$ like $\propto \xi^{-3/2} \exp \left (- \frac{2 u m^2}{3 \xi \, k \cdot p} \right )$ at $u \ge 1$.

Hybrid neutron stars in the mass-radius diagram
[arXiv:2106.06986]
 GO
We present a systematic investigation of the possible locations for the special point (SP), a unique feature of hybrid neutron stars in the mass-radius. The study is performed within the two-phase approach where the high-density (quark matter) phase is described by the constant-sound-speed (CSS) equation of state (EoS) and the nuclear matter phase around saturation density is varied from very soft (APR) to stiff (DD2 with excluded nucleon volume.

Conceptual Design Report for the LUXE Experiment
[DESY 21-016; DESY-21-016; arXiv:2102.02032]
 GO
This Conceptual Design Report describes LUXE (Laser Und XFEL Experiment), an experimental campaign that aims to combine the high-quality and high-energy electron beam of the European XFEL with a powerful laser to explore the uncharted terrain of quantum electrodynamics characterised by both high energy and high intensity. We will reach this hitherto inaccessible regime of quantum physics by analysing high-energy electron-photon and photon-photon interactions in the extreme environment provided by an intense laser focus.

Study of energy response and resolution of the ATLAS Tile Calorimeter to hadrons of energies from 16 to 30 GeV
[arXiv:2102.04088]
 GO
Three spare modules of the ATLAS Tile Calorimeter were exposed to test beams from the Super Proton Synchrotron accelerator at CERN in 2017. The measurements of the energy response and resolution of the detector to positive pions and kaons and protons with energy in the range 16 to 30 GeV are reported. [...]

Trinucleon form factors with relativistic multirankseparable kernels
[arXiv:2102.06061]
 GO
This paper studies elastic electron-trinucleon scattering in the relativistic impulse approximation. The amplitudes for a trinucleon have been obtainedby solving the relativistic generalization of the Faddeev equations with amultirank separable kernel of the nucleon-nucleon interactions [...]

A High Pressure Time Projection Chamber with Optical Readout
[arXiv:2102.06643]
 GO
Measurements of proton-nucleus scattering and high resolution neutrino-nucleus interaction imaging are key to reduce neutrino oscillation systematic uncertainties in future experiments. A High Pressure Time Projection Chamber (HPTPC) prototype has been constructed and operated at Royal Holloway University of London and CERN as a first step in the development of a HPTPC capable of performing these measurements as part of a future long-baseline neutrino oscillation experiment such as the Deep Underground Neutrino Experiment.

Differential equations and Feynman integrals
[arXiv:2102.07424]
 GO
The role of differential equations in the process of calculating Feynman integrals is shown. An example of a diagram is given, in the calculation of which the method of differential equations was introduced, the properties of the inverse-mass-expansion coefficients are shown, and modern methods based on differential equations are considered..

Split Casimir operator for simple Lie algebras, solutions of Yang-Baxter equations and Vogel parameters
[arXiv:2102.08258]
 GO
We construct characteristic identities for the split (polarized) Casimir operators of the simple Lie algebras in defining (minimal fundamental) and adjoint representations. By means of these characteristic identities, for all simple Lie algebras we derive explicit formulae for invariant projectors onto irreducible subrepresentations in T^{\otimes 2} in two cases, when T is the defining and the adjoint representation.
