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 $\phi$

Monte Carlo modeling of radiation dose from radiation therapy with superficial x‐rays

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Introduction Superficial x‐rays (50–100 kVp) are used for treating non‐melanoma skin cancer and intraoperative radiation therapy (IORT). At these energies, the photoelectric effect significantly increases absorbed dose to bone compared to soft tissue.

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.

Evaluation of dosimetric and spatial accuracy of a virtual cone technique for radiosurgery using linac‐integrated CBCT‐based polymer gel dosimetry

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose This study evaluates the dosimetric and geometric precision of a virtual cone technique using CBCT‐based polymer gel dosimetry, enabling radiation delivery, and imaging readout within an identical spatial coordinate system. Methods We created a C# script for a virtual cone technique that generates a treatment plan with 10 gantry arcs ...

Production of Dark Sector Particles via Resonant Positron Annihilation on Atomic Electrons

open access: yesPhysical Review Letters
Resonant positron annihilation on atomic electrons provides a powerful method to search for light new particles coupled to e+e−. Reliable estimates of production rates require a detailed characterization of electron momentum distributions. We describe a general method that harnesses the target material Compton profile to properly include electron ...

Measurement of e + e − → ωη′ cross sections at s $$ \sqrt{s} $$ = 2.000 to 3.080 GeV

open access: yesJournal of High Energy Physics
We measured the Born cross sections for the process e + e − → ωη′ at 22 center-of-mass energies from 2.000 to 3.080 GeV with the BESIII detector at the BEPCII collider. We observed a resonant structure with a statistical significance of 9.6σ.

A search for new resonances in multiple final states with a high transverse momentum Z boson in s $$ \sqrt{s} $$ = 13 TeV pp collisions with the ATLAS detector

open access: yesJournal of High Energy Physics, 2023
A generic search for resonances is performed with events containing a Z boson with transverse momentum greater than 100 GeV, decaying into e + e − or μ + μ − . The analysed data collected with the ATLAS detector in proton-proton collisions at a centre-of-

Artificial Receptor in Synthetic Cells Performs Transmembrane Activation of Proteolysis

open access: yesAdvanced Biology, EarlyView.
Transmembrane signaling is the hallmark of living cells and is among the highest challenges for the design of synthetic cells. Herein, an artificial receptor based on the chemistry of self‐immolative linkers is used to communicate information across the lipid bilayer, for transmembrane activation of enzymatic activity. Abstract The design of artificial,

Entropy production, energy loss and currents in adiabatically rocked thermal ratchets [PDF]

open access: yes, 2003
We study the nature of currents, input energy and entropy production in different types of adiabatically rocked ratchets using the method of stochastic energetics. The currents exhibit a peak as a function of noise strength.
