Ground state particle-particle correlations and double beta decay [PDF]

open access: yes, 2001
A self-consistent formalism for the double beta decay of Fermi type is provided. The particle-particle channel of the two-body interaction is considered first in the mean field equations and then in the QRPA.

General equation for Zeno-like effects in spontaneous exponential decay [PDF]

open access: yesPhysics Letters A, V.260, No 6 (1999), P. 441-446, 1999
It was shown that different mechanisms of perturbation of spontaneous decay constant: inelastic interaction of emitted particles with particle detector, decay onto an unstable level, Rabi transition from the final state of decay (electromagnetic field domination) and some others are really the special kinds of one general effect - perturbation of decay

Transverse Observables and Mass Determination at Hadron Colliders [PDF]

open access: yes, 2007
I consider the two-body decay of a particle at a hadron collider into a visible and an invisible particle, generalizing $W \to e \nu$, where the masses of the decaying particle and the invisible decay particle are, {\em a priori}, unknown.

Alpha decay measured in single-particle units as a manifestation of nuclear collectivity

open access: yesPhysics Letters B, 2021
A salient feature of quantum mechanics is the inherent property of collective quantum motion, when apparent independent quasiparticles move in highly correlated trajectories, resulting in strongly enhanced transition probabilities.

Comparative Analysis of Nuclear Matrix Elements of 0νβ+β+ Decay and Muon Capture in 106Cd

open access: yesFrontiers in Physics, 2021
Comparative analyses of the nuclear matrix elements (NMEs) related to the 0νβ+β+ decay of 106Cd to the ground state of 106Pd and the ordinary muon capture (OMC) in 106Cd are performed.

Scaling laws for the decay of multiqubit entanglement [PDF]

open access: yes, 2008
We investigate the decay of entanglement of generalized N-particle Greenberger-Horne-Zeilinger (GHZ) states interacting with independent reservoirs. Scaling laws for the decay of entanglement and for its finite-time extinction (sudden death) are derived ...

Proton decay

open access: yesNuclear Physics B, 2023
Proton decay is a hypothetical form of particle decay in which protons are assumed to decay into lighter particles. This form of decay has yet to be detected.

Decay modes of two repulsively interacting bosons

open access: yes, 2011
We study the decay of two repulsively interacting bosons tunneling through a delta potential barrier by direct numerical solution of the time-dependent Schr\"odinger equation. The solutions are analyzed according to the regions of particle presence: both

Search for a 33.9 MeV/c^2 Neutral Particle in Pion Decay [PDF]

open access: yes, 1999
The E815 (NuTeV) neutrino experiment has performed a search for a 33.9 MeV/c^2 weakly-interacting neutral particle produced in pion decay. Such a particle may be responsible for an anomaly in the timing distribution of neutrino interactions in the KARMEN

Radiative corrections to neutron and nuclear β-decays: a serious kinematics problem in the literature

open access: yesJournal of High Energy Physics, 2023
We report a serious kinematics problem in the bremsstrahlung photon part of the order-α outer (model independent) radiative correction calculations for those neutron (and nuclear beta) decay observables (like electron-neutrino correlation parameter ...
