Detection of Black Holes01:10

Detection of Black Holes

2.2K
Although black holes were theoretically postulated in the 1920s, they remained outside the domain of observational astronomy until the 1970s.
Their closest cousins are neutron stars, which are composed almost entirely of neutrons packed against each other, making them extremely dense. A neutron star has the same mass as the Sun but its diameter is only a few kilometers. Therefore, the escape velocity from their surface is close to the speed of light.
Not until the 1960s, when the first neutron...

Atomic Nuclei: Nuclear Magnetic Moment00:59

Atomic Nuclei: Nuclear Magnetic Moment

1.2K
All atomic nuclei are positively charged. When they have a nonzero spin, they behave like rotating charges. As a consequence of their charge and spin, these nuclei generate a magnetic field (B). This, in turn, gives rise to a magnetic moment (μ), which is randomly oriented in the absence of an external magnetic field. When an external magnetic field (B0) is applied, the magnetic moment vectors can align with the field or against it in 2 + 1 orientations. A hydrogen nucleus, which is just a...

Atomic Nuclei: Magnetic Resonance

688
The number of nuclear spins aligned in the lower energy state is slightly greater than those in the higher energy state. In the presence of an external magnetic field, as the spins precess at the Larmor frequency, the excess population results in a net magnetization oriented along the z axis. When a pulse or a short burst of radio waves at the Larmor frequency is applied along the x axis, the coupling of frequencies causes resonance and flips the nuclear spins of the excess population from the...

Nuclear Transmutation03:20

Nuclear Transmutation

17.6K
Nuclear transmutation is the conversion of one nuclide into another. It can occur by the radioactive decay of a nucleus, or the reaction of a nucleus with another particle. The first manmade nucleus was produced in Ernest Rutherford’s laboratory in 1919 by a transmutation reaction, the bombardment of one type of nuclei with other nuclei or with neutrons. Rutherford bombarded nitrogen-14 atoms with high-speed α particles from a natural radioactive isotope of radium and observed...

Mass Analyzers: Common Types01:19

Mass Analyzers: Common Types

655
The quadrupole mass analyzer consists of four cylindrical metal rods arranged in a diamond carrying a DC voltage and a radio-frequency AC voltage. The motion of ions through the quadrupole depends on the field strength, causing only ions of a certain m/z to resonate successfully and strike the detector at a given field strength. Though the transmission rate for these analyzers is high, the exact elemental composition of the sample is not determined because of low resolution; however, they are...

Diamagnetic Shielding of Nuclei: Local Diamagnetic Current01:14

Diamagnetic Shielding of Nuclei: Local Diamagnetic Current

902
An applied magnetic field causes the electrons present in the molecule to circulate, setting up a local diamagnetic current within the molecule. The local diamagnetic current arising from circulating sigma-bonding electrons induces a magnetic field, Blocal that opposes the applied magnetic field, B0. The effective magnetic field experienced by these nuclei is given by the difference between the applied and local magnetic fields in a phenomenon called local diamagnetic shielding. Essentially,...

Area of Science:

  • Particle Physics
  • Cosmology
  • Astrophysics

Background:

  • Theories beyond the Standard Model predict new stable particles that could constitute dark matter.
  • These particles may evade direct detection due to rapid thermalization in dense environments.

Purpose of the Study:

  • To explore the potential of large-volume neutrino telescopes for discovering or constraining new dark matter particles.
  • To investigate the annihilation signals of stable relics interacting with visible matter.

Main Methods:

  • Analyzing the annihilation of stable relic particles into visible matter within neutrino telescopes.
  • Constraining models using existing Super-Kamiokande data on dinucleon annihilation.
  • Developing an explicit model of secluded dark matter coupled to a dark photon.

Main Results:

  • Annihilation signals are most pronounced for relic particles in the GeV mass range.
  • Existing Super-Kamiokande searches provide stringent constraints on these particles.
  • The proposed method yields novel bounds complementary to other experimental constraints.

Conclusions:

  • Neutrino telescopes offer a novel avenue for dark matter searches.
  • Stable relics in the GeV range are significantly constrained by current data.
  • The secluded dark matter model with a dark photon is effectively bounded by this approach.
