The technical challenges of the Large Hadron Collider [PDF]

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2015
The Large Hadron Collider (LHC) is a 27 km circumference hadron collider, built at CERN to explore the energy frontier of particle physics. Approved in 1994, it was commissioned and began operation for data taking in 2009. The design and construction of the LHC presented many design, engineering and logistical challenges which involved pushing a number

Charmonium production in ultra-peripheral heavy ion collisions with two-photon processes

open access: yesNuclear Physics B, 2017
We calculate the production of large-pT charmonium and narrow resonance state (exotic charmonium) in proton–proton, proton–nucleus, and nucleus–nucleus collisions with the semi-coherent two-photon interactions at Relativistic Heavy Ion Collider (RHIC ...

Ferrites with a Minimized Secondary Electron Yield

open access: yesAdvanced Science, Volume 12, Issue 10, March 13, 2025.
Ferrites are a key material in particle accelerators and space science, exposing them to high energy electrons and leading to multipacting, charging and electron cloud formation. Laser engineered surface structures are shown to dramatically reduce the secondary electron yield of ferrite eliminating these issues.

Using Neural Networks with data Quantization for time Series Analysis in LHC Superconducting Magnets

open access: yesInternational Journal of Applied Mathematics and Computer Science, 2019
The aim of this paper is to present a model based on the recurrent neural network (RNN) architecture, the long short-term memory (LSTM) in particular, for modeling the work parameters of Large Hadron Collider (LHC) super-conducting magnets.

Doubly-charged particles at the Large Hadron Collider

open access: yes, 2013
In this work we investigate the production and signatures of doubly-charged particles at the Large Hadron Collider. We start with the Standard Model particle content and representations and add generic doubly-charged exotic particles.

Exploring Dark Photon Production and Kinetic Mixing Constraints in Heavy‐Ion Collisions

open access: yesAstronomische Nachrichten, Volume 346, Issue 3-4, March-May 2025.
ABSTRACT Vector U‐bosons, often referred to as “dark photons,” are potential candidates for mediating dark matter interactions. In this study, we outline a procedure to derive theoretical constraints on the upper bound of the kinetic mixing parameter ϵ2MU$$ {\upvarepsilon}^2\left({M}_U\right) $$ using dilepton data from heavy‐ion from SIS to RHIC ...

A Large Hadron Electron Collider at the LHC [PDF]

open access: yesProceedings of the XVI International Workshop on Deep-Inelastic Scattering and Related Topics, 2008
Following HERA, the LHeC represents a new ep/eA collider of much increased luminosity and energies. Using the LHC, with Ep between 1 and 7TeV, complemented by an electron ring or linac, with Ee possibly up to 140 GeV, a new range of DIS opens up and precise investigations of the proton structure and new phenomena at TeV energies become possible.

Exclusive Z0 photoproduction at the Large Hadron Collider and the Future Circular Collider

open access: yesNuclear Physics B, 2020
In this paper we present a comprehensive analysis of the exclusive Z0 photoproduction in pp, pPb and PbPb collisions for the energies of the Large Hadron Collider (LHC) and of the proposed Future Circular Collider (FCC).
