Measurement of χ c1(3872) production in proton-proton collisions at s $$ \sqrt{s} $$ = 8 and 13 TeV

open access: yesJournal of High Energy Physics, 2022
The production cross-section of the χ c1(3872) state relative to the ψ(2S) meson is measured using proton-proton collision data collected with the LHCb experiment at centre-of-mass energies of s $$ \sqrt{s} $$ = 8 and 13 TeV, corresponding to integrated ...

Analytical Description of the Distributions of Primary and Secondary Cosmogenic Particles

open access: yesAdvances in High Energy Physics, Volume 2026, Issue 1, 2026.
In this work, we present an analytical description of the energy distributions of primary and secondary cosmogenic particles on Earth in terms of parameters having clear physical meaning. A modified power law is assumed for energy distributions, incorporating terms such as energy loss/decay, which are effective at low energies, and a source term, which

Hadron showers in a digital hadron calorimeter [PDF]

open access: yesJournal of Instrumentation, 2009
A small prototype of a finely granulated digital hadron calorimeter with Resistive Plate Chambers as active elements was exposed to positive pions of 1 >. 16 GeV energy from the Fermilab test beam. The event selection separates events with mostly non-interacting particles and events with hadronic showers which initiated in the front part of the ...

On the nature of the N* and Δ resonances via coupled-channel dynamics [PDF]

open access: yesEPJ Web of Conferences
This talk focuses on a recent work aiming at determining the composition of certain N* and Δ resonances, i.e. whether they are compact states formed directly by quarks and gluons, or composite generated from the mesonbaryon interaction.

MOS and RREA Processes in Thunderclouds: Intensities and Spectral Shapes

open access: yesGeophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract The Relativistic Runaway Electron Avalanche (RREA) is the primary mechanism for enhancing atmospheric electron and gamma‐ray fluxes when the electric field exceeds a density‐dependent threshold. Another, non‐threshold process—Modification of the Electron Energy Spectrum (MOS)—occurs when subcritical fields energize ambient electrons, shifting ...

Reconstruction of semileptonically decaying beauty hadrons produced in high energy pp collisions

open access: yes, 2017
It is well known that in $b$ hadron decays with a single unreconstructible final state particle, the decay kinematics can be solved up to a quadratic ambiguity, without any knowledge of the $b$ hadron momentum. We present a method to infer the momenta of

Polarization Effects In Hadron-Hadron Scatterings

open access: yesCumhuriyet Science Journal, 2018
In the case of diffraction scattering of hadrons by hadrons, a nonzeropolarization of the scattered particles arises, which is related to thelogarithmic derivative of the differential scattering cross section.Polarization changes sign in those reactions ...

In‐House Production of POFs Using Electrospinning, Melt‐Electrospinning and Melt‐Spinning for Cell‐Level Resolution Radiation Detectors

open access: yesJournal of Applied Polymer Science, Volume 142, Issue 48, December 20, 2025.
Optical transmission along a melt‐spun polystyrene microfiber with a diemeter of 80 um. ABSTRACT Since their discovery in 1965, scintillating plastic optical fibers have been used as radiation detectors in nuclear and high‐energy physics research.

HADRONIC ATOMS

open access: yesLe Journal de Physique Colloques, 1972
We mention briefly two new results in the study of muonic atoms concerning the measurement of spectroscopic quadrupole moments and the study of radiative corrections with muonic atoms. As an introduction to the subject proper, we review shortly some of the basic properties of hadronic atoms and their theoretical analysis.
