We present the physics program of Belle II experiment, located on intensity frontier SuperKEKB $e^+e^-$ collider. collected its first collisions in 2018, and is expected to operate for next decade. It anticipated collect 50/ab collision data over lifetime. This book outcome a joint effort collaborators theorists through theory interface platform (B2TiP), an that commenced 2014. The aim B2TiP was elucidate potential impacts program, which includes wide scope topics: B physics, charm, tau,...

The article presents an approach for calculating pass-by sound pressure radiated from railway wheels in the time domain using moving Green's functions. functions are obtained by Finite Element (FE) and Boundary (BE) methods frequency domain, subsequent inverse Fourier transform, followed convolution with a series of rolling contact forces to obtain signals. However, traditional BE computationally expensive due low structural damping wheel, necessitating high resolution. To overcome this...
Psychoacoustic experiments have shown that directional properties of the direct sound, salient reflections, and late reverberation an acoustic room response can a distinct influence on auditory perception given room. Spatial impulse responses (SRIRs) capture those thus are used for direction-dependent analysis virtual rendering. This work proposes subspace method decomposes SRIRs into part, which comprises sound residual, to facilitate enhanced rendering methods by providing individual...
A bstract We present an updated fit of supersymmetric SO(10) models to quark and lepton masses mixing parameters. Including latest results from lattice QCD determinations neutrino oscillation data, we show that fits neglecting threshold corrections are strongly disfavoured in our setup. Only when include these find good points. χ 2 -profiles for the parameters, which setup thresholds related third generation fermions exhibit two rather narrow minima.
Spherica1 microphone array (SMA) recordings are particularly suited for dynamic binaural rendering as the signals can be decomposed into a spherical harmonic (SH) representation that freely rotated to match head orientation of listener. The such SMA is non-trivial task SH impaired due truncation decomposition order, spatial aliasing and gain limitation employed radial filters. perceptually most relevant consequence this an alteration magnitude transfer function at high frequencies....
Smart glasses are increasingly recognized as a key medium for augmented reality, offering hands-free platform with integrated microphones and non-ear-occluding loudspeakers to seamlessly mix virtual sound sources into the real-world acoustic scene. To convincingly integrate sources, room rendering of must match acoustics. Information about user's environment however is typically not available. This work uses microphone array in pair smart blindly identify binaural impulse responses (BRIRs)...
In recent years three-, four- and five-loop beta functions have been computed for various phenomenologically interesting models. However, most of these results not implemented in easy to use software packages. $\texttt{RGE++}$ bridges this gap by providing a flexible, template-based, $\texttt{C++}$ library solve renormalisation group equations. Furthermore, we implement the available Standard Model, minimal supersymmetric extension Model two-Higgs-doublet models, as well right-handed...
We propose a method for the decomposition of measured directional room impulse responses (DRIRs) into prominent reflections and residual. The comprises obtaining fingerprint time-frequency signal that given reflection carries, imposing this on plane-wave prototype exhibits same propagation direction as reflection, finally subtracting from DRIR. Our main contributions are formulation problem spatial subtraction well incorporation order truncation, aliasing regularization radial filters...
Radiative corrections with new heavy particles coupling to Higgs doublets destabilize the electroweak scale and require an ad-hoc counterterm cancelling large loop contribution. If mass m1 of these in TeV range, this feature constitutes "little fine-tuning problem". We consider case that new-physics spectrum has a little hierarchy two particle scales m1, m2 = O(10 m1) no tree-level couplings heavier doublets. As concrete example we study (next-to-)minimal supersymmetric standard model...
The sound radiation from railway wheels is typically the dominant source of rolling noise above about 2 kHz to 4 kHz.To calculate wheels, numerical approaches such as Boundary Element Method can be used. However, those are computationally expensive as, firstly, short wavelengths in structure demand a fine spatial discretisation and, secondly, low structural damping requires very high frequency resolution. When simulating pass-by signals, computational load further increased many positions...
Der erste Teil dieser Arbeit untersucht den Yukawa Sektor eines minimalen supersymmetrischen SO($_{10}$) Modells. Eine globale Analyse ergibt, dass die GUT Vorhersagen fur Fermionmassen und deren Minschungsobservablen von jungsten Daten aus Neutrinoexperimenten Gittersimulationen angefochten werden. Weiterhin zeigt sich, moglichen Werte SUSY Schwellenkorrekturen zu Kopplungen erheblich eingeschrankt sind. Der zweite befasst sich mit Quantenkorrekturen schweren Gluinos zum...
