A UV resonance line echo from a shell around a hydrogen-poor superluminous supernova [PDF]

open access: yesNature Astronomy, 2018
Hydrogen-poor superluminous supernovae (SLSN-I) are a class of rare and energetic explosions that have been discovered in untargeted transient surveys in the past decade1,2.

Determination of the strong coupling constant α S(mZ) from measurements of inclusive W ± and Z boson production cross sections in proton-proton collisions at s $$ \sqrt{\mathrm{s}} $$ = 7 and 8 TeV

open access: yesJournal of High Energy Physics, 2020
Twelve measurements of inclusive cross sections of W ± and Z boson production, performed in proton-proton collisions at centre-of-mass energies of 7 and 8 TeV, are compared with perturbative quantum chromodynamics calculations at next-to-next- to-leading

Photo-catalytic hydrogen production over Au/g-C3N4: effect of gold particle dispersion and morphology.

open access: yesPhysical Chemistry, Chemical Physics - PCCP, 2019
Metal/semiconductor interactions affect electron transfer rates and this is central to photocatalytic hydrogen ion reduction. While this interaction has been studied in great detail on metal oxide semiconductors, not much is known of Au particles on top ...

Observation of e + e − → π 0 π 0 ψ 2(3823)

open access: yesJournal of High Energy Physics, 2023
Using a data sample corresponding to an integrated luminosity of 11.3 fb −1 collected at center-of-mass energies from 4.23 to 4.70 GeV with the BESIII detector, we observe the process e + e − → π 0 π 0 ψ 2(3823) for the first time with a statistical ...

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 $\phi$

Sub-GeV dark matter production at fixed-target experiments [PDF]

open access: yes, 2020
We analyze the sensitivity of fixed-target experiments to sub-GeV thermal relic dark matter models, accounting for variations in both mediator and dark matter mass, and including dark matter production through both on- and off-shell mediators.

Cross section measurements of the processes e + e − → ωπ 0 and ωη at center-of-mass energies between 3.773 and 4.701 GeV

open access: yesJournal of High Energy Physics, 2022
The Born cross sections of the processes e + e − → ωπ 0 and e + e − → ωη are measured at center-of-mass energies between 3.773 and 4.701 GeV using a total integrated luminosity of 22.7 fb −1 collected with the BESIII detector operating at the BEPCII ...
