Thanks to their weakly-interacting nature, neutrinos traverse cosmic distances without being deflected. They can provide information about far astrophysical object as a complementary probe of the Universe with respect to other messengers such as multi-wavelength light, charged cosmic rays and gravitational waves. Here, an overview of the neutrino telescopes currently operating in the...
In a Schwarzschild, metric that includes torsion effects, the corresponding event horizon is calculated and from that, we calculate the entropy of such black hole as a function is spin density that event horizon depends upon. Next using the entropy expression in terms of the number of information bits we calculate the dependence of spin density on the formation number N. Furthermore, we...
With the help of computer modelling, b-jets were identified under certain kinematical restrictions on the transverse momentum and pseudorapidity at the LHC with 14 TeV energy. The calculations were carried out in the framework of the MSSM model with the parameters determined from the latest experimental data. The selection of the most high-energy jets at the optimum value of their departure...
We propose a model describing the scattering of hadrons as bound states of their constituent quarks. We analyze the role of simultaneity in measurements of the characteristics of different particles for the description of relativistic quantum systems. On the basis of this analysis we conclude that the relativistic scattering of bound states of particles should not be described by the fields...
The ALICE experiment is designed to study the QCD properties of the matter created in proton-proton and heavy-ion collisions at the LHC.
Neutral mesons can be reconstructed in ALICE in a wide $p_{\textrm T}$ range via two-photon decays.
Neutral meson measurements give an opportunity to validate NLO or NNLO pQCD calculations and to constrain the parton fragmentation functions. Neutral meson...
In tensor analysis we deal with tensor objects that are different in nature: scalars, vectors, tensors of rank n. When the basis (four non-collinear non-coplanar basis vectors) is introduced at each point of space-time, all these objects may be treated as the n-polylinear combinations of the basis vectors with scalar coefficients. This means that the variation of any Lagrangian with tensor...
In this contribution, I review growing interest in large area fast timing detectors based on Low-Gain Avalanche Detectors (LGAD) with a timing resolution of 30-50ps. Combining precise timing of minimum ionizing particles (MIPs) with tracking significantly benefits performance of the detector by improving resolution and background rejection. Large-scale high-precision timing detectors have to...

The Jiangmen Underground Neutrino Observatory (JUNO) is a next generation multi-purpose antineutrino detector currently under construction in Jiangmen, China.
The central detector, containing 20 kton of liquid scintillator, is equipped with ~18,000 20 inch and ~25,000 3 inch PMTs. Measuring the reactor antineutrinos of two powerplants at a baseline of 53 km with an unprecedented energy...
The inclusive production of four isolated charged leptons in pp collisions is analysed for the presence of hard double-parton scattering, using a dataset corresponding to 20.2 fb-1, recorded with the ATLAS detector at the LHC at centre-of-mass energy of 8 TeV. In the four-lepton invariant-mass range of 80 < M4l < 1000 GeV, an artificial neural network is used to enhance the separation between...
The KArlsruhe TRItium Neutrino (KATRIN) experiment is a large-scale experiment with the objective to determine the effective electron anti-neutrino mass with an unprecedented sensitivity of 0.2 eV/c² at 90% C.L. in a model-independent way. The measurement method is based on precision $\beta$-decay spectroscopy of molecular tritium.
The experimental setup consists of a high luminosity...
PANDA (Antiproton Annihilation at Darmstadt) is a fixed target experiment that is going to address a wide range open questions in the hadron physics sector by studying the interactions between antiprotons with high momenta and a stationary proton target. The PANDA detector is currently under construction and will be situated in the HESR (High Energy Storage Ring) that is part of the future...
A complementary way to obtain some information about the high-energy scattering processes is by passing from the momentum transfer to the impact parameter space through a Fourier-Bessel transform. In this work, we analyze the spatial structure of the interaction region of two colliding protons in the light of the recent TOTEM data using a dipole Regge model. The discrepancies of the...
We discuss the fact that the measured multiplicity distributions, P(N), after closer inspection, exhibit some peculiarly enhanced void probability and oscillatory behavior of the corresponding modified combinants. Both of these features can shed new light on our uderstanding of the multipaerticle production processes, and both were so far basically neglected (or ignored) in the usual analysis of data.
