Summary
We introduce dark matter internal pair production (DIPP), a novel method for detecting dark matter at particle accelerators. This process produces unique lepton pairs, offering a clear signal distinct from background noise.
Area of Science:
- Particle Physics
- Cosmology
- Astrophysics
Background:
- Dark matter remains undetected, necessitating new detection strategies.
- Existing detection methods have limitations in probing certain dark matter models.
Purpose of the Study:
- Introduce and validate dark matter internal pair production (DIPP) as a novel detection mechanism.
- Assess the efficacy of DIPP at beam dump facilities like DarkQuest, SBND, and DUNE ND.
Main Methods:
- Simulate dark matter scattering via virtual photon exchange, producing lepton-antilepton pairs.
- Analyze electron-positron and muon-antimuon signatures from DIPP.
- Compare DIPP sensitivity with existing recoil-based limits.
Main Results:
- DIPP is highly effective for probing dark matter models, especially at DUNE ND and DarkQuest.
- DIPP sensitivity at DUNE ND surpasses existing limits from electron and nuclear recoil.
- The mechanism is versatile, probing various dark matter models with different final states.
Conclusions:
- DIPP offers a powerful new avenue for dark matter detection at beam dump experiments.
- This mechanism provides enhanced sensitivity for specific dark matter candidates and couplings.
- Future experiments can leverage DIPP to explore a broader parameter space of dark matter.

2.3K
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.

01:26Diamagnetism
2.5K
Materials consisting of paired electrons have zero net magnetic moments. However, when these materials are placed under an external magnetic field, the moments opposite to the field are induced. Such materials are called diamagnets. Diamagnetism is the response of the diamagnets when placed in an external magnetic field.
Diamagnetism was discovered by Anton Brugmans in 1778 when he observed that bismuth gets repelled by magnetic fields, thus theorizing that diamagnets get repelled by magnets....

In a beam of charged particles created by a heated cathode, the particles move at different speeds. However, many applications need a beam with uniform particle speeds. An arrangement known as a velocity selector uses electric and magnetic fields to pick particles with a particular speed from the beam.
A particle with charge q, speed v, and mass m enters an area from the top, where the magnetic and electric fields are perpendicular both to the particle's motion and to one another. The...

01:04¹³C NMR: ¹H–¹³C Decoupling
1.2K
The probability of having two carbon-13 atoms next to each other is negligible because of the low natural abundance of carbon-13. Consequently, peak splitting due to carbon-carbon spin-spin coupling is not observed in spectra. However, protons up to three sigma bonds away split the carbon signal according to the n+1 rule, resulting in complicated spectra.
A broadband decoupling technique is used to simplify these complex, sometimes overlapping, signals. Broadband decoupling relies on a...

01:14Diamagnetic Shielding of Nuclei: Local Diamagnetic Current
962
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,...

01:12Interaction of EM Radiation with Matter: Spectroscopy
2.0K
Electromagnetic (EM) radiation can be considered an oscillating electric and magnetic field propagating through a medium that can interact with matter in its path. The electric field in the radiation can interact with electrical charges in the atoms or molecules in the matter. On the other hand, the magnetic field can interact with the magnetic field in the atomic nucleus. The study of the interaction between electromagnetic radiation and matter is termed spectroscopy. Spectroscopy is the study...
