Search for heavy resonances decaying to ZZ or ZW and axion-like particles mediating nonresonant ZZ or ZH production at s? = 13 TeV

open access: yes, 2022
A search has been performed for heavy resonances decaying to ZZ or ZW and for axion-like particles (ALPs) mediating nonresonant ZZ or ZH production, in final states with two charged leptons (? = e, ?) produced by the decay of a Z boson, and two quarks produced by the decay of a Z, W, or Higgs boson H. The analysis is sensitive to resonances with masses

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

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 ...

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 ...

Effect of the Generalized Uncertainty Principle on Post-Inflation Preheating [PDF]

open access: yes, 2011
We examine effects of the Generalized Uncertainty Principle, predicted by various theories of quantum gravity to replace the Heisenberg's uncertainty principle near the Planck scale, on post inflation preheating in cosmology, and show that it can predict
