Matching the Vilkovisky–DeWitt Effective Action of Quantum Gravity to String Theory

open access: yesFortschritte der Physik, Volume 72, Issue 12, December 2024.
Abstract In this work, the matching of the Vilkovisky–DeWitt effective action of quantum gravity is discussedwith an example of an ultra‐violet complete theory of quantum gravity. The authors show how this matching enables a calculation of the local Wilson coefficients of the effective action. Several examples in string theory are provided.

Localization and entanglement through scattering measurements [PDF]

open access: yesarXiv, 2011
We study the emergence of localization and entanglement in many-body systems as a result of scattering measurements. We show that consecutive scattering measurements on a many-body system can produce superposition states in position space. The resulting states are signaled in the scattering distribution and these states are robust under continued ...

Transverse-Spin and Transverse-Momentum Effects in High-Energy Processes

open access: yes, 2010
The state of the art concerning transverse-spin and transverse-momentum phenomena in hard hadronic reactions is reviewed. An account is given of single-spin and azimuthal asymmetries in semiinclusive deep inelastic scattering, e^+ e^- annihilation, Drell-

Recent Developments in Halide Perovskite Nanocrystals for Indirect X‐ray Detection

open access: yesAdvanced Materials Technologies, Volume 9, Issue 20, October 21, 2024.
Perovskite nanocrystals act as scintillators under X‐ray illumination with different conversion yield, stability, or decay times and outperform commercial materials, depending on their composition, host matrix, and luminescence process. Besides the lead halide perovskites, there are lead‐free alternatives providing self‐trapped exciton emission ...

From theory to experiment: hadron electromagnetic form factors in space-like and time-like regions [PDF]

open access: yes, 2006
Hadron electromagnetic form factors contain dynamical information on the intrinsic structure of the hadrons. The pioneering work developed at the Kharkov Physical-Technical Institute in the 60's on the relation between the polarized cross section and ...

Measurement of the Z(→ ℓ + ℓ − )γ production cross-section in pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2020
The production of a prompt photon in association with a Z boson is studied in proton-proton collisions at a centre-of-mass energy s $$ \sqrt{s} $$ = 13 TeV. The analysis uses a data sample with an integrated luminosity of 139 fb −1 collected by the ATLAS

Measurements of W + W − + ≥ 1 jet production cross-sections in pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2021
Fiducial and differential cross-section measurements of W + W − production in association with at least one hadronic jet are presented. These measurements are sensitive to the properties of electroweak-boson self-interactions and provide a test of ...

Aspects of electron scattering, the elastic, and the inelastic [PDF]

open access: yesarXiv, 2017
A electron of mass $m$, when electrically scatters of nucleus, of mass $M$, transfers momentum $q$ to the nucleus. The energy lost by electron is more than the energy gained by the nucleus. The resulting energy goes in exciting the atom to a higher energy state as in Frank Hertz experiment and sodium, neon, mercury vapor lamps, or ionization of atom as

Search for a scalar partner of the top quark in the jets plus missing transverse momentum final state at s=13 $$ \sqrt{s}=13 $$ TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2017
A search for pair production of a scalar partner of the top quark in events with four or more jets plus missing transverse momentum is presented. An analysis of 36.1 fb−1 of s=13 $$ \sqrt{s}=13 $$ TeV proton-proton collisions collected using the ATLAS ...
