Over the last five decades, many outstanding questions in particle physics have been answered, leading to the Standard Model (SM) and its spectacular confirmation with the discovery of the Higgs boson in 2012, which would supply the heart to this theory. Now the hunt is on for a deeper theory of reality. To answer this question, Europe, Japan, the US and China have proposed plans for building...
Until 1993, the Kharkiv Institute of Physics and Technology was the largest scientific center in Ukraine where nuclear physics research was conducted using beams of γ-quanta, electrons, protons, and other charged particles. The institute had a number of unique accelerator facilities: the largest linear accelerators in Europe, LU-2000 and LU-300, the H-100 storage facility, and a number of...
Celebrating the 70th Anniversary of the CERN KINR Team enjoys the “PAST, PRESENT and FUTURE” horizons of its eclusive data, p scientific life participating at CERN, taking and analyzing construction and upgrade activities of the experimental setups with a clear roadmap to the end of this century!
In this report, we present KINR activity at CERN with emphasis on LHCb Collaboration.
LHCb...
Anomalous contributions to magnetic and electric dipole moments of the tau lepton have brought renewed interest in development of new CP violating signatures in tau-pair production at Belle II and the LHC. We discuss spin-correlation formalism for production of polarized tau leptons in electron-positron and photon-photon processes, and in proton-proton collisions. Such studies can give...
Production of muon pairs in junction with hadronic jets is studied under conditions of LHC experiments [1-3]. Hard parton processes are simulated with MadGraph5_aMC@NLO [4,5] at the tree level and at Next-to-Leading order (NLO) in perturbative quantum chromodynamics (pQCD). The parton processes have n=0,…,4 light quarks or gluons in the final states. The generated parton events are showered...
One of the objectives of current and future collider experiments in the GeV range, such as the Beam Energy Scan program at the Relativistic Heavy Ion Collider (RHIC BES) and the Compressed Baryonic Matter experiment at the Facility for Antiproton and Ion Research (FAIR CBM), is to study the phase diagram of Quantum Chromodynamics. These experiments aim to detect signals of a phase transition...
Rare decays are widely recognized as an excellent laboratory for testing the Standard Model at high precision and searching for the New Physics phenomena [1]. The flavor-changing neutral currents, like b→s l^+ l^- transitions, are of special interest. They are forbidden at the tree level in the Standard Model and, therefore, can only proceed via higher-order diagrams. If experimental deviation...
The GRAiNITA is a novel type of electromagnetic calorimeter with a detection volume filled with high atomic number scintillator grains of about millimetre in size, interfiled with high-density liquid and wavelength shifting (WLS) optical fibres. The calorimeter is being developed to meet the requirements of future collider experiments.
The energy resolution (R = $\frac{σ_E}{E}$) of the...
Unconventional baryonic and mesonic states represent a topical issue in contemporary hadron physics. New results from the charm-quark sector indicate the existence of multi-quark objects beyond the quark-antiquark and 3-quark configurations (mesons and baryons) known from particle physics textbooks, which reveal themselves through unexpectedly narrow structures in energy. They are interpreted...
Production of strange mesons (KS) and baryons (Λ) have been studied with the LHCb in p-Pb collisions at √s = 5 TeV. Cross sections as well as their ratios (Λ-bar/KS, Λ-bar/Λ) have been measured differentially in transverse momentum between 0.15 and 7.0 GeV/c and rapidity in the ranges 1.5 < y < 4.0 and −5 < y < −2.5. The nuclear modification factors are measured for given transverse momentum...
Within the framework of the mean field model, the thermodynamics of the relativistic scalar system of interacting particles and antiparticles in the presence of a Bose-Einstein condensate is investigated. It is assumed that the total isospin (charge) density is conserved. It is shown that the particle-antiparticle boson system reveals four types of phase transitions into the condensate phase....
This study investigates the effectiveness of tungsten matrix collimators for spatially fractionated radiation therapy (SFRT). The research combines experimental studies and Monte Carlo simulations to evaluate the fractionation of gamma-ray and electron beams. The results demonstrate the possibility of achieving high fractionation indicators (PVDR over 10) for irradiation of shallow...
