Rare exclusive semileptonic b -> s transitions in the Standard Model

open access: yes, 1997
We study long-distance effects in rare exclusive semileptonic decays B -> (K, K*) (l+ l-, nu bar{nu}) and analyze dilepton spectra and asymmetries within the framework of the Standard Model. The form factors, describing the meson transition amplitudes of

Preparing VTS for the MASS Era: A Machine Learning-Based VTSO Recruitment Model

open access: yesJournal of Marine Science and Engineering
As the maritime industry transitions toward Maritime Autonomous Surface Ships (MASS), Vessel Traffic Service Operators (VTSOs) face new challenges in managing mixed traffic of conventional and autonomous vessels.

B--> K^* l^+ l^- decay in the two Higgs doublet model with flavor changing neutral currents

open access: yes, 1999
We study the decay width, forward-backward asymmetry and the longitudinal lepton polarization for the exclusive decay B --> K^* l^+ l^- in the two Higgs doublet model with three level flavor changing neutral currents (model III) and analyse the ...

Branching Ratios for $B \to K^* \gamma$ and $B \to \rho \gamma$ Decays in Next-to-Leading Order in the Large Eneregy Effective Theory [PDF]

open access: yes, 2002
We calculate the so-called hard spectator corrections in ${\cal O} (\alpha_s)$ in the leading-twist approximation to the decay widths for $B \to K^{*} \gamma$ and $B \to \rho \gamma$ decays and their charge conjugates, using the Large Energy Effective ...

Flavor Changing Neutral Currents in a Realistic Composite Technicolor Model

open access: yes, 1992
We consider the phenomenology of a composite technicolor model proposed recently by Georgi. Composite technicolor interactions produce four-quark operators in the low energy theory that contribute to flavor changing neutral current processes.

Premission and postmission simulation studies of the foot-controlled maneuvering unit for Skylab experiment T-020 [PDF]

open access: yes
A Skylab experiment was conducted to study the maneuvering capabilities of astronauts using a relatively simple self-locomotive device, referred to as the foot-controlled maneuvering unit, and to evaluate the effectiveness of ground-based facilities ...

CP violation in B_s mixing from heavy Higgs exchange

open access: yes, 2010
The anomalous dimuon charge asymmetry reported by the D0 Collaboration may be due to the tree-level exchange of some spin-0 particles that mediate CP violation in B_s-\bar{B}_s meson mixing.

Introduction to flavour physics

open access: yes, 2019
We give a brief introduction to flavour physics. The first part covers the flavour structure of the Standard Model, how the Kobayashi-Maskawa mechanism is tested and provides examples of searches for new physics using flavour observables, such as meson ...

A Formalism for Scalable Maritime Traffic Monitoring and Explainable Anomaly Detection and Resolution at Vessel Traffic Services

open access: yesJournal of Physics: Conference Series
Vessel traffic service (VTS) centres around the globe monitor and manage the ship traffic in their areas of responsibility and respond to arising unsafe or inefficient situations.
