Comparison Between Electrical And Gravitational Forces01:24

Comparison Between Electrical And Gravitational Forces

There are four fundamental forces in nature: the gravitational force, the electromagnetic force, the strong nuclear force, and the weak nuclear force. To compare the numerical strengths of the first two, take two particles of the same kind. Since electrons are fundamental particles, they are a good example.
Since both are inverse square law forces, the distance gets canceled when the ratio of the two forces is considered. Instead, the ratio of the electrical and gravitational forces depends on...
Symmetry in Maxwell's Equations01:28

Symmetry in Maxwell's Equations

Once the fields have been calculated using Maxwell's four equations, the Lorentz force equation gives the force that the fields exert on a charged particle moving with a certain velocity. The Lorentz force equation combines the force of the electric field and of the magnetic field on the moving charge. Maxwell's equations and the Lorentz force law together encompass all the laws of electricity and magnetism. The symmetry that Maxwell introduced into his mathematical framework may not be...
Coulomb's Law and The Principle of Superposition01:15

Coulomb's Law and The Principle of Superposition

Coulomb's Law describes the force experienced by two point charges under each other's presence. But what if there are more than two charges? For example, if there is a third charge, does it experience a force that is a simple combination of the individual forces due to the first two charges? Can it be described mathematically?
The Principle of Superposition answers the question. Yes, Coulomb's Law applies to each pair of charges, and the net force on each charge is the vector sum of the...
Types Of Superconductors01:28

Types Of Superconductors

A superconductor is a substance that offers zero resistance to the electric current when it drops below a critical temperature. Zero resistance is not the only interesting phenomenon as materials reach their transition temperatures. A second effect is the exclusion of magnetic fields. This is known as the Meissner effect. A light, permanent magnet placed over a superconducting sample will levitate in a stable position above the superconductor. High-speed trains that levitate on strong...
Spin–Spin Coupling: Two-Bond Coupling (Geminal Coupling)01:20

Spin–Spin Coupling: Two-Bond Coupling (Geminal Coupling)

Two NMR-active nuclei bonded to a central atom can be involved in geminal or two-bond coupling. Geminal coupling is commonly seen between diastereotopic protons in chiral molecules and unsymmetrical alkenes, among others.
The central atom need not be NMR-active because its electrons are affected by the electron polarization of the spin-active atoms. However, spin information is transmitted less effectively than in one-bond coupling, and 2J values are usually weaker than 1J values. The energy of...
The Principle of Superposition and the Gravitational Field01:17

The Principle of Superposition and the Gravitational Field

The principle of superposition applies to gravitational forces of objects that are sufficiently far apart. It states that the net gravitational force on a point object is the vector sum of the gravitational forces on it due to various objects. The principle helps calculate the force by listing the individual forces and then vectorially summing them up. However, it should be noted that the principle of superposition is not always apparent. In the presence of a second force, the first force could...

Area of Science:

  • Particle Physics
  • Cosmology
  • Quantum Field Theory

Background:

  • Supersymmetric electroweak baryogenesis is a leading mechanism for generating the observed baryon asymmetry in the universe.
  • Previous models often simplified interactions, potentially missing crucial dependencies.

Purpose of the Study:

  • To analyze quantum transport equations for supersymmetric electroweak baryogenesis with previously neglected bottom and tau Yukawa interactions.
  • To investigate the impact of these interactions on the cosmic baryon asymmetry and its dependence on superpartner spectra.

Main Methods:

  • Quantum transport equations were analyzed.
  • The role of bottom and tau Yukawa interactions was incorporated.
  • The dependence of baryon asymmetry on the spectrum of third-generation quark and lepton superpartners was examined.

Main Results:

  • A previously unrecognized dependence of cosmic baryon asymmetry on the spectrum of third-generation quark and lepton superpartners was identified.
  • For fixed CP-violating phases, baryon asymmetry magnitude and sign vary with squark and slepton masses.
  • Light, right-handed top and bottom quark superpartners can lead to baryon number creation dominated by third-generation lepton interactions.

Conclusions:

  • Bottom and tau Yukawa interactions are crucial for accurately modeling supersymmetric electroweak baryogenesis.
  • The spectrum of superpartners, particularly third-generation ones, plays a significant role in determining the baryon asymmetry.
  • Future studies should consider these interactions for a more complete understanding of baryogenesis.
