Resonances in coupled channels in nuclear and particle physics

open access: closedPhysics Reports, 1982
Abstract Starting from first principles this report gives account of the important latest developments on resonances in coupled channels in nuclear and hadronic physics. It also gives many new results which have remained hitherto unpublished. All types of poles of the S matrix are considered in coupled-channel problems, on all Riemann sheets.

New Physics in di-boson resonances and long-lived particles with ATLAS and CMS: Latest Run 1 and early Run 2 results

open access: closed, 2017
This paper reports several results from the corresponding presentation given by the author at the IFAE 2016 conference in Genova. Because of the large number of studies reported there and the limited space available for these proceedings, only a small fraction of the results will be cited here.

Gasdynamic electron cyclotron ion sources: Basic physics, applications, and diagnostic techniques.

Review of Scientific Instruments, 2022
The gasdynamic electron cyclotron resonance (ECR) ion source is a type of the device in which the ionization efficiency is achieved primarily due to a high plasma density.

Resonance Coupling in an Individual Gold Nanorod-Monolayer WS2 Heterostructure: Photoluminescence Enhancement with Spectral Broadening.

ACS Nano, 2020
Recently, resonance coupling between plasmonic nanocavity and two-dimensional semiconductors has attracted considerable attention. Most of the previous studies have focused on demonstrating this effect with light scattering or reflection spectroscopy ...

Physical structure, optical resonance, and surface-enhanced Raman scattering of silver-island films on suspended polymer latex particles [PDF]

open access: possibleAnalytical Chemistry, 1993
A new approach to producing SERS activity on dispersed particles is described. Silver islands are deposited onto submicron latex and glass particles, and the particles are dispersed into aqueous suspensions. The physical structure of the metal islands is investigated by transmission electron and atomic force microscopies and compared with the optical ...

Drift‐Bounce Resonance Between Charged Particles and Ultralow Frequency Waves: Theory and Observations

Journal of Geophysical Research: Space Physics, 2020
Ultralow frequency (ULF) waves have long been known to resonate with magnetospheric charged particles through their drift and bounce motions. Most research interest has focused on the resonance with drift motion, which can accelerate charged particles at

Physical mechanism of wave-particle resonances in a curved magnetic field

The Physics of Fluids, 1982
The physical mechanism of wave-particle resonances in a curved magnetic field is investigated. Specifically, the energy exchange process between a wave and resonant curvature drifting particles is discussed (i.e., ω∼k⋅Vc, where Vc = v2∥/RcΩ is the curvature drift, Rc is the radius of curvature of the magnetic field, and Ω is the cyclotron frequency).

Physical mechanism of wave-particle resonances in an inhomogeneous magnetic field. I. Linear theory

The Physics of Fluids, 1981
A physical description is given of the wave-particle resonance which can occur when particles undergoing a ∇ B drift are in phase with a wave propagating across the magnetic field (i.e., ω ∼ k⋅V∇ B, where V∇ B is the ∇ B drift velocity). Specifically, the physics of the energy exchange mechanism is discussed and a general equation for the wave damping ...

Observations in particle physics from two neutrinos to the standard model.

Science, 1989
The two-neutrino experiment established a relationship between particles, muon and muon neutrino, electron and electron neutrino, which evolved into the standard model of particle physics.
