Multi-GPU Accelerated High-Fidelity Simulations of Beam-Beam Effects in Particle Colliders
<p>Numerical simulation of beam-beam effects in particle colliders are crucial in understanding and the design of future machines such as electron-ion colliders (JLEIC), linac-ring machines (eRHIC) or LHeC. These simulations model the non-linear collision dynamics of two counter rotating beams in …

Cosmological constraints using 2- and 3-point correlations with meerkat, the ska and other surveys
… and modified gravity. We account for telescope beam effects, instrumental noise, foreground avoidance, the Alcock-Paczynski effect, and theoretical modeling errors in the correlators. The investigation also includes assessments of 21-cm clustering bias up to the second order.

Impurity Incorporation and Redistribution During the Growth of Single-Crystal Semiconductors by Molecular Beam Epitaxy: A Theoretical and Experimental Study
… single-crystal semiconductors grown by molecular beam epitaxy (MBE). Experimental results include Sn doping of GaAs, Si doping of Ga(,x)Al(,x)As (where x ranges from 0 to 1), Zn-ion doping of GaAs, In doping of Si, and In and As ion doping of Si. The results demonstrate segregation of dopant atoms …

Third-order QCD corrections to heavy quark pair production near threshold
… There are two ways to incorporate higher order effects, one is to calculate the full next order in the fixed order approach, another possibility is to resum large logarithms. In this work, the fixed order calculation has been extended to the third order in perturbation theory for the QCD …

Beam Dynamics Challenges in the Muon g-2 Experiment
… muons. This thesis presents a selection of muon beam dynamics effects which are critical for reaching the experiment precision goal. A system of detectors assists with the challenging beam injection into the storage ring, and a measurement of the injected beam provides input for simulating the …
