Multi-Step Production of a Diphoton Resonance [PDF]

open access: yes, 2016
Among the questions that would be raised by the observation of a new resonance at the LHC, particularly pressing are those concerning the production mechanism: What is the initial state?

Search for sub-eV axion-like resonance states via stimulated quasi-parallel laser collisions with the parameterization including fully asymmetric collisional geometry

open access: yesJournal of High Energy Physics, 2021
We have searched for axion-like resonance states by colliding optical photons in a focused laser field (creation beam) by adding another laser field (inducing beam) for stimulation of the resonance decays, where frequency-converted signal photons can be ...

Twisted particle collisions: A new tool for spin physics [PDF]

open access: yes, 2020
Collisions of twisted particles --- that is, non-plane-wave states of photons, electrons, or any other particle, equipped with a non-zero orbital angular momentum (OAM) with respect to its propagation direction --- offer novel ways to probe particle ...

Observation of e + e − → ηψ(2S) at center-of-mass energies from 4.236 to 4.600 GeV

open access: yesJournal of High Energy Physics, 2021
Using a total of 5.25 fb −1 of e + e − collision data with center-of-mass energies from 4.236 to 4.600 GeV, we report the first observation of the process e + e − → ηψ(2S) with a statistical significance of 4.9 standard deviations.

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 ...

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.

Probing Planckian physics: Resonant production of particles during inflation and features in the primordial power spectrum [PDF]

open access: yesPhysical Review D, 2000
The phenomenon of resonant production of particles {\it after} inflation has received much attention in the past few years. In a new application of resonant production of particles, we consider the effect of a resonance {\em during} inflation. We show that if the inflaton is coupled to a massive particle, resonant production of the particle during ...
