Observation of the decay ψ(3686) → Σ − Σ ¯ + $$ {\Sigma}^{-}{\overline{\Sigma}}^{+} $$ and measurement of its angular distribution

open access: yesJournal of High Energy Physics, 2022
Using (448.1 ± 2.9) × 106 ψ(3686) events collected with the BESIII detector at the BEPCII collider, the decay ψ(3686) → Σ − Σ ¯ + $$ {\Sigma}^{-}{\overline{\Sigma}}^{+} $$ is observed for the first time with a branching fraction of (2.82 ± 0.04stat.

New narrow N*(1685) resonance: review of observations

open access: yes, 2014
The recent Review of Particle Physics [1] includes a new narrow N*(1685) resonance. Its properties, the narrow width and the strong photoexcitation on the neutron, are unusual.

Evaluation of synaptotagmin‐1 action models by all‐atom molecular dynamics simulations

open access: yesFEBS Open Bio, EarlyView.
We used molecular dynamics simulations to test models proposing that synaptotagmin‐1 facilitates membrane fusion by perturbing lipid bilayers, inducing membrane curvature and/or bridging membranes. The simulations show that synaptotagmin‐1 C2‐domains placed near the site of fusion hinder the ability of SNARE complexes to bring the membranes together ...

Coherent photoproduction of ρ 0 vector mesons in ultra-peripheral Pb-Pb collisions at s NN $$ \sqrt{{\mathrm{s}}_{\mathrm{NN}}} $$ = 5.02 TeV

open access: yesJournal of High Energy Physics, 2020
Cross sections for the coherent photoproduction of ρ 0 vector mesons in ultra-peripheral Pb-Pb collisions at s NN $$ \sqrt{{\mathrm{s}}_{\mathrm{NN}}} $$ = 5.02 TeV are reported. The measurements, which rely on the π + π − decay channel, are presented in

High-dimensional anomaly detection with radiative return in e+e− collisions

open access: yesJournal of High Energy Physics, 2022
Experiments at a future e + e − collider will be able to search for new particles with masses below the nominal centre-of-mass energy by analyzing collisions with initial-state radiation (radiative return).

A stopped Delta-Matter Source in Heavy Ion Collisions at 10 GeV/n

open access: yes, 1994
We predict the formation of highly dense baryon-rich resonance matter in Au+Au collisions at AGS energies. The final pion yields show observable signs for resonance matter.

Particle production in the oscillating inflation model [PDF]

open access: yes, 2000
We investigate the particle production of a scalar field $\chi$ coupled to an inflaton field $\phi$ ($g^2\phi^2\chi^2/2$) in the {\it oscillating inflation} model, which was recently proposed by Damour and Mukhanov. Although the fluctuation of the $\phi$

Determination of appropriate energy threshold range for accurate estimation of effective atomic number considering statistical uncertainty in photon‐counting techniques

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose The energy threshold is an important parameter for precise material identification employing photon‐counting techniques. However, in such applications, the appropriate energy threshold has not been clarified. Therefore, we aimed to determine the appropriate energy threshold range for precise material identification, focusing on ...

Two electron entanglement enhancement by an inelastic scattering process

open access: yes, 2007
In order to assess inelastic effects on two fermion entanglement production, we address an exactly solvable two-particle scattering problem where the target is an excitable scatterer.
