Future colliders based on a modulated proton bunch driven plasma wakefield acceleration [PDF]

arXiv, 2012
Recent simulation shows that a self-modulated high energy proton bunch can excite a large amplitude plasma wakefield and accelerate an externally injected electron bunch to the energy frontier in a single stage acceleration through a long plasma channel. Based on this scheme, future colliders, either an electron-positron linear collider (e+-e- collider)

Size‐Dependent Multiexciton Dynamics Governs Scintillation From Perovskite Quantum Dots

Advanced Materials, Volume 37, Issue 5, February 5, 2025.
Quantum‐confined nano scintillators are gaining interest in radiation detection. Understanding the nanoscale scintillation mechanism and key material parameters is crucial. These open questions are addressed by studying the scintillation of CsPbBr3 quantum dots.

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

International 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.

Probing Electroweak Top Quark Couplings at Hadron and Lepton Colliders [PDF]

arXiv, 2005
The International Linear Collider (ILC) will be able to precisely measure the electroweak couplings of the top in e+e- -> tt~. We compare the limits which can be achieved at the ILC with those which can be obtained in tt~gamma$ and tt~Z production at the Large Hadron Collider (LHC).

Studies of Parity Violation in Atoms

Annalen der Physik, Volume 537, Issue 2, February 2025.
This article provides an overview of atomic parity violation (APV), emphasizing its role in testing the Standard Model and probing new physics. The review discusses manifestations of APV, including nuclear‐spin‐independent and dependent effects, and explores isotopic comparison as a method for precision measurements.

Analysis of the anomalous quartic $WWWW$ couplings at the LHeC and the FCC-he [PDF]

, 2019
The quartic gauge boson couplings that identify the strengths of the gauge boson self-interactions are exactly determined by the non-Abelian gauge nature of the Standard Model. The examination of these couplings at $ep$ collisions with high center-of-mass energy and high integrated luminosity provides an important opportunity to test the validity of ...

Progress in the Determination of the Partonic Structure of the Proton

, 2013
We review the current state of the art in the determination of the parton substructure of the nucleon, as expressed in terms of parton distribution functions (PDFs), and probed in high-energy lepton-hadron and hadron-hadron collisions, and we assess ...

Seesaw Neutrino Signals at the Large Hadron Collider

, 2010
We discuss the scenario with gauge singlet fermions (right-handed neutrinos) accessible at the energy of the Large Hadron Collider. The singlet fermions generate tiny neutrino masses via the seesaw mechanism and also have sizable couplings to the ...

Big Science and the Large Hadron Collider [PDF]

Physics in Perspective, 2012
The Large Hadron Collider (LHC), the particle accelerator operating at CERN, is probably the most complex and ambitious scientific project ever accomplished by humanity. The sheer size of the enterprise, in terms of financial and human resources, naturally raises the question whether society should support such costly basic-research programs. I address

Traveling wave method for simulating geometric beam coupling impedance of a beam screen with pumping holes

Physical Review Accelerators and Beams, 2019
In particle accelerators, pumping holes in a vacuum chamber can be a source of unwanted broadband coupling impedance, leading to beam instabilities. Analytical methods have been previously developed to estimate the impedance of holes in circularlike ...
