¹H NMR: Complex Splitting

1.4K
A proton M that is coupled to a proton X results in doublet signals for M. However, NMR-active nuclei can be simultaneously coupled to more than one nonequivalent nucleus. When M is coupled to a second proton A, such as in styrene oxide, each peak in the doublet is split into another doublet.
Splitting diagrams or splitting tree diagrams are routinely used to depict such complex couplings. While drawing splitting diagrams, the splitting with the larger coupling constant is usually applied...

Spin–Spin Coupling Constant: Overview

1.1K
In bromoethane, the three methyl protons are coupled to the two methylene protons that are three bonds away. In accordance with the n+1 rule, the signal from the methyl protons is split into three peaks with 1:2:1 relative intensities. The methylene protons appear as a quartet, with the relative intensities of 1:3:3:1.
Qualitatively, any spin plus-half nucleus polarizes the spins of its electrons to the minus-half state. Consequently, the paired electron in the hydrogen–carbon bond must...

Compacting Factor test

298
The compacting factor test is a method used to assess the workability of concrete. It is  especially suitable for concrete mixes containing aggregates up to one and a half inches in size. This test involves specialized equipment consisting of two truncated cone-shaped hoppers and a cylinder, all with polished interior surfaces to minimize friction.
The procedure begins by placing concrete into the upper hopper without any compaction. Once filled, the bottom door of this hopper is opened,...

Moment-of-Momentum Equation01:09

Moment-of-Momentum Equation

215
The moment-of-momentum equation is a critical tool for analyzing the torque produced by the rotating blades of a wind turbine. This equation is derived by applying Newton's second law to a fluid particle, which states that the rate of change of linear momentum is equal to the external force acting on the particle.

Singularity Functions for Bending Moment01:18

Singularity Functions for Bending Moment

298
Singularity functions simplify the representation of bending moments in beams subjected to discontinuous loading, allowing the use of a single mathematical expression. For a supported beam AB, with uniform loading from its midpoint M to the right side end B, the approach involves conceptual 'cuts' at specific points to determine the bending moment in each segment. By cutting the beam at a point between A and M, the bending moment for the segment before reaching midpoint M is represented...

Area of Science:

  • High Energy Physics
  • Quantum Chromodynamics (QCD)

Background:

  • W boson production at hadron colliders is sensitive to transverse momentum dependent distributions (TMD) at low boson transverse momentum.
  • Non-perturbative QCD contributions are often extrapolated from Z boson production.

Purpose of the Study:

  • To use existing TMD extractions from Drell-Yan and semi-inclusive deep inelastic scattering (SIDIS) to check and predict W boson production.
  • To analyze transverse momentum dependent cross sections for W and Z bosons under various fiducial cuts and kinematic conditions.

Main Methods:

  • Utilized an existing extraction of TMDs, derived using the Artemide code, incorporating data from Drell-Yan and SIDIS processes.
  • Applied fiducial cuts and kinematic power corrections to calculate transverse momentum dependent cross sections across different vector boson transverse mass intervals.
  • Studied both W and Z boson production, as well as their charge asymmetries.

Main Results:

  • Compared predictions with recent experimental data from ATLAS and CMS, as well as results from the Tevatron.
  • Demonstrated the utility of existing TMDs for W boson production studies.
  • Showcased the consistency of TMD predictions across different vector boson types and kinematic regimes.

Conclusions:

  • The study encourages further experimental and phenomenological investigations into TMDs for W boson production.
  • Validated the use of TMDs extracted from other processes for W boson physics.
  • Highlights the potential for deeper understanding of non-perturbative QCD effects in electroweak boson production.
