Production of pions, kaons, and protons as a function of the relative transverse activity classifier in pp collisions at s $$ \sqrt{s} $$ = 13 TeV

open access: yesJournal of High Energy Physics, 2023
The production of π ± , K ± , and p ¯ p $$ \left(\overline{\textrm{p}}\right)\textrm{p} $$ is measured in pp collisions at s $$ \sqrt{s} $$ = 13 TeV in different topological regions of the events.

Spin and Polarization in High-Energy Hadron-Hadron and Lepton-Hadron Scattering [PDF]

open access: yesSymmetry, 2020
The role of spin degrees of freedom in high-energy hadron-hadron and lepton-hadron scattering is reviewed with emphasis on the dominant role of soft, diffractive, non-perturbative effects. Explicit models based on analyticity and Regge-pole theory, including the pomeron trajectory (gluon exchange in the t channel) are discussed.

Hadrons and nuclei [PDF]

open access: yesThe European Physical Journal A, 2019
This document is one of a series of whitepapers from the USQCD collaboration. Here, we discuss opportunities for lattice QCD calculations related to the structure and spectroscopy of hadrons and nuclei. An overview of recent lattice calculations of the structure of the proton and other hadrons is presented along with prospects for future extensions ...

Monte Carlo study on fetal dose assessment for carbon beam craniospinal irradiation during pregnancy

open access: yesMedical Physics, Volume 53, Issue 3, March 2026.
Abstract Background Radiotherapy may be suggested for pregnant cancer patients when treatment cannot be delayed, with careful targeting to minimize fetal dose. Considering that a successful case for a pregnant patient treated with proton beam craniospinal irradiation (CSI) was reported, carbon therapy can be also considered applicable for the CSI ...

Measurement of J/Ψ production in pp collisions at √s=7 TeV [PDF]

open access: yes, 2011
The production of J/psi mesons in proton-proton collisions at root s = 7 TeV is studied with the LHCb detector at the LHC. The differential cross-section for prompt J/psi production is measured as a function of the J/psi transverse momentum p(T) and ...

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.

Model pluralism for logic

open access: yesNoûs, Volume 60, Issue 1, Page 136-160, March 2026.
Abstract It is well‐recognized in the sciences that a multitude of nonequivalent models are used by researchers to fulfill a range of goals, even for the same target system, a result known broadly as model pluralism. The possibility of the same form of pluralism occurring in logic, however, has not been adequately considered.

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 ...

Galactic Cosmic Ray Ionization on Uranus; Geomagnetic Latitude Dependencies

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract Galactic Cosmic Rays (GCRs) are a major source of atmospheric ionization, influencing ion abundance, aerosol formation, and electrical processes. GCR‐induced effects are expected to be more pronounced on Uranus than planets closer to the Sun for two reasons; reduced solar irradiance, and weaker solar modulation of incident GCR.

Operational results with fast automatic beam-based LHC collimator alignment [PDF]

open access: yes, 2013
The CERN Large Hadron Collider (LHC) is the largest and highest-energy particle accelerator ever built. It is designed to collide particles at a centre-of-mass energy of 14 TeV to explore the fundamental forces and constituents of matter.
