Fermi-LAT Observation of PSR B1259-63 during Its 2021 Periastron Passage

Universe, 2021
PSR B1259-63 is a γ-ray binary system, where the compact object is a pulsar. The system has an orbital period of 1236.7 days and shows peculiar γ-ray flares (in 100 MeV–300 GeV) after its periastron time.

Particle and nuclear physics with high energy leptons [PDF]

Nuclear Physics A, 2000
In high centre-of-mass energy lepton-nucleon collisions the space-time time resolution of partonic processes can be {\it fine-tuned} within a dynamical range which is unattainable in hadronic collisions. Replacing nucleons by nuclei of variable atomic number enables one to tune the strength of colour forces.

Study on Internal Strain Distribution of the High-Field Nb₃Sn Superconducting Accelerator Magnets With Homogenization Theory

IEEE Access, 2022
To fabricate 10–16 Tesla high-field accelerator magnets, the high-Jc Nb3Sn superconductor is one of the most practical choices. However, it is a brittle material and is strain-sensitive.

Complex Langevin analysis of 2D U(1) gauge theory on a torus with a θ term

Journal of High Energy Physics, 2020
Monte Carlo simulation of gauge theories with a θ term is known to be extremely difficult due to the sign problem. Recently there has been major progress in solving this problem based on the idea of complexifying dynamical variables. Here we consider the
