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.

Measurement of the differential Drell-Yan cross section in proton-proton collisions at s $$ \sqrt{\mathrm{s}} $$ = 13 TeV

open access: yesJournal of High Energy Physics, 2019
Measurements of the differential cross section for the Drell-Yan process, based on proton-proton collision data at a centre-of-mass energy of 13 TeV, collected by the CMS experiment, are presented.

Measurements of differential production cross sections for a Z boson in association with jets in pp collisions at s = 8 $$ \sqrt{s}=8 $$ TeV

open access: yesJournal of High Energy Physics, 2017
Cross sections for the production of a Z boson in association with jets in proton-proton collisions at a centre-of-mass energy of s = 8 $$ \sqrt{s}=8 $$ TeV are measured using a data sample collected by the CMS experiment at the LHC corresponding to 19.6

Extraction of kinetic freeze-out properties and effect of resonance decays

open access: yes, 2005
We present STAR results from identified particle spectra measured in $\sqrt{s_{NN}}$ = 62.4 GeV Au-Au collisions. Particle production and system dynamics are compared to results at $\sqrt{s_{NN}}$ = 200 GeV.

Evidence for Planck-scale resonant particle production during inflation from the CMB power spectrum [PDF]

open access: yesThe Fourteenth Marcel Grossmann Meeting, 2017
The power spectrum of the cosmic microwave background from both the {\it Planck} and {\it WMAP} data exhibits a slight dip for multipoles in the range of $l= 10-30$. We show that such a dip could be the result of the resonant creation of massive particles that couple to the inflaton field.

On Features and Nongaussianity from Inflationary Particle Production

open access: yes, 2010
Interactions between the inflaton and any additional fields can lead to isolated bursts of particle production during inflation (for example from parametric resonance or a phase transition).

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

Measurement of ω meson production in pp collisions at s $$ \sqrt{s} $$ = 13 TeV

open access: yesJournal of High Energy Physics
The p T-differential cross section of ω meson production in pp collisions at s $$ \sqrt{s} $$ = 13 TeV at midrapidity (|y| < 0.5) was measured with the ALICE detector at the LHC, covering an unprecedented transverse-momentum range of 1.6 < p T < 50 GeV/c.

Axion-like particle searches at DarkQuest

open access: yesJournal of High Energy Physics, 2022
Axion-like particles (ALPs) interacting with the Standard Model can be abundantly produced in proton beam fixed-target experiments. Looking for their displaced decays is therefore an effective search strategy for ALPs with a mass in the MeV to GeV range.
