Exclusive cone jet algorithms for high energy particle colliders
… momenta and show that it reconstructs these particles with efficiencies between 60% and 80% without any additional substructure techniques, and maintains this efficiency over a wide kinematic range. This algorithm provides many key advantages over traditional jet algorithms that make it …

Automating methods to improve precision in Monte-Carlo event generation for particle colliders
… for a theoretical description of high energy particle scattering experiments. It focuses on fixed order perturbative calculations, i.e. on matrix elements and scattering cross sections at leading and next-to-leading order. For the leading order a number of algorithms for the matrix element …

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 …

The vacuum chamber in the interaction region of particle colliders : a historical study and developments implemented in the LHCb experiment at CERN
El colisionador de protenes actualmente en construcción en el CERN llamado LHC (Large Hadron Collider) se convertirá en el más potente acelerador jamas construido con una energía por protón de 7 TeV. Se prevé que esta en operación en 2007. Constará de 4 grandes experimentos uno de los cuales, LHCb, …

New Tools In The Search For Supersymmetry
… has thrust humanity into the TeV-scale era of particle physics, and with it we have discovered a new Higgs-like particle and set stronger limits on possible theories of supersymmetry and beyond-the-Standard-Model physics. But while the experimental community continues to improve their searches …

Exploration of models of dark matter and portals to new physics
Although the Standard Model of particle physics has seen tremendous experimental success, there remain still unanswered questions. One such question is the nature of dark matter, which has been only observed through its gravitational effects and yet comprises about 80% of all matter in the …

Precision Metrology with Ytterbium Ions for New Physics Search
… Complementary to high-energy searches with particle colliders, the atomic clocks are used to place stringent bounds on tests of fundamental physics. One of the possible candidates for physics beyond the Standard Model is a carrier of a fifth force. Such a hypothetical particle that mediates …

Investigation and Optimization of a New Compact Superconducting Cavity for Deflecting and Crabbing Applications
… head-on collision at the interaction point in particle colliders in order to increase the luminosity. The early uses of the deflecting structures have been in the early 1960s: these structures were disk loaded structures operating at room temperature. The crabbing structure which was installed …

Studies in positron and gamma ray production for future facilities
The next generation of particle colliders after the LHC (Large Hadron Collider) at CERN are likely to be high-precision electron positron colliders such as the ILC (International Linear Collider) or CLIC (Compact Linear Collider). This next generation of colliders will give new scope to explore …

Engineering relativistic fermions in condensed matter systems
When the speed of the particle is much less than the speed of light, non-relativistic classical mechanics faithfully describes the motion of the particle. Analogously, using wave-particle duality, the non-relativistic description of classical mechanics may be applied to describe the motion of a …
