Divergence and Curl of Electric Field01:25

Divergence and Curl of Electric Field

6.8K
The divergence of a vector is a measure of how much the vector spreads out (diverges) from a point. For example, an electric field vector diverges from the positive charge and converges at the negative charge. The divergence of an electric field is derived using Gauss's law and is equal to the charge density divided by the permittivity of space. Mathematically, it is expressed as

Electric Dipoles and Dipole Moment

5.9K
Consider two charges of equal magnitude but opposite signs. If they cannot be separated by an external electric field, the system is called a permanent dipole. For example, the water molecule is a dipole, making it a good solvent.
Theoretically, studying electric dipoles leads to understanding why the resultant electric forces around us are weak. Since electric forces are strong, remnant net charges are rare. Hence, the interaction between dipoles helps us understand electrical interactions in...

Spin–Spin Coupling Constant: Overview

1.2K
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...

Spin–Spin Coupling: Three-Bond Coupling (Vicinal Coupling)01:22

Spin–Spin Coupling: Three-Bond Coupling (Vicinal Coupling)

1.3K
Vicinal or three-bond coupling is commonly observed between protons attached to adjacent carbons. Here, nuclear spin information is primarily transferred via electron spin interactions between adjacent C‑H bond orbitals. This generally favors the antiparallel arrangement of spins, so 3J values are usually positive.
The extent of coupling depends on the C‑C bond length, the two H‑C‑C angles, any electron-withdrawing substituents, and the dihedral angle between the involved orbitals. The...

Atomic Radii and Effective Nuclear Charge

60.2K
The elements in groups of the periodic table exhibit similar chemical behavior. This similarity occurs because the members of a group have the same number and distribution of electrons in their valence shells.

Area of Science:

  • High Energy Physics
  • Quantum Chromodynamics
  • Particle Physics

Background:

  • Inclusive cross section calculations are crucial for understanding particle interactions.
  • Perturbative Quantum Chromodynamics (pQCD) provides a framework for these calculations.
  • Previous calculations have reached next-to-next-to-leading order.

Purpose of the Study:

  • To present phenomenological results for the inclusive cross section of lepton pair production.
  • To compute this cross section at next-to-next-to-next-to-leading order in pQCD.
  • To analyze the impact of these higher-order corrections on theoretical predictions.

Main Methods:

  • Phenomenological analysis of lepton pair production.
  • Calculation within perturbative Quantum Chromodynamics (pQCD).
  • Evaluation at next-to-next-to-next-to-leading order (N3LO).

Main Results:

  • The hadronic cross section receives corrections at the percent level.
  • Residual dependence on perturbative scales is significantly reduced.
  • The uncertainty band from scale variation is not contained within the previous order's band, indicating a notable change in theoretical uncertainty.

Conclusions:

  • The N3LO calculation provides a more precise prediction for lepton pair production.
  • The observed behavior of the uncertainty band highlights the importance of higher-order corrections.
  • These findings contribute to a better understanding of electroweak processes in particle physics.
