چکیده

Within the quasi-two-body decay model, we study localized CP violation and branching fraction of four-body when pair invariant masses are , with pairs being dominated by resonances, respectively. When dealing dynamical functions these modeled Bugg Gounaris-Sakurai function, Flatté formalism LASS lineshape, respectively, while others described relativistic Breit-Wigner function. Adopting end point divergence parameters our predicted results based on hypothetical structures for scalar mesons in QCD factorization approach. Meanwhile, calculate violating asymmetries fractions two-body decays all individual Our theoretical consistent available experimental data, remaining predictions await testing future high precision experiments.

Two phenomenological studies of place

We introduce our initial investigations into the phenomenology of place as part of the BENOGO project. BENOGO is concerned with giving people the experience of ‘being there without going there’. Employing a state-of-the-art mixture of photorealistic, real time rendered images, three-dimensional soundscapes and augmented reality to create a sense of place. The work reported in this paper we desc...

Phenomenological Studies on Supersymmetry and The Strong Force

The possibility to simulate lepton number violating supersymmetric models has been introduced into the recently updated Pythia event generator, now containing 1278 decay channels of SUSY particles into SM particles via lepton number violating interactions. This generator has been used in combination with the AtlFast detector simulation to study the impact of lepton number violation (L/ ) on eve...

Analytical and Phenomenological Studies of Rotating Turbulence

A framework, which combines mathematical analysis, closure theory, and phenomenological treatment, is developed to study the spectral transfer process and reduction of dimensionality in turbulent ows that are subject to rotation. First, we outline a mathematical procedure that is particularly appropriate for problems with two disparate time scales. The approach which is based on the Green's met...

Decay ring status / studies

The aim of "beta-beams" is to produce highly energetic pure electron neutrino and anti-neutrino beams coming from β-decay of radioactive ions. In CERN baseline, after accelerating, the ions 6 He 2+ and 18 Ne 10+ are stored in a racetrack-shaped-decay ring until they are lost [1]. Consequently, the injection compensates the losses which occurred between two cycles. Two main loss sources were ide...
