Thomson's e/m Experiment

7.3K
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 magnetic...

Nuclear Transmutation03:20

Nuclear Transmutation

20.9K
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...

Tandem Mass Spectrometry

2.8K
Tandem mass spectrometry is a technique that uses multiple mass analyzers in series to obtain a higher selectivity and reduce chemical noise during analyte detection. Instruments with multiple analyzers separated by an interaction cell enable secondary fragmentation and selected study of the fragment ions.Secondary fragmentations occur in the interaction cell and can be induced by various factors. Fragmentation induced by collision with inert gases, such as N2, Ar, He, etc., is called...

Mass Analyzers: Common Types

1.7K
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...

Peptide Identification Using Tandem Mass Spectrometry

8.7K
Tandem mass spectrometry, also known as MS/MS or MS2, is an analytical technique that employs two mass analyzers. Essentially it is a series of mass spectrometers that helps isolate a particular biomolecule and then helps study its chemical properties.
This technique helps gather information regarding the protein from which the peptide was obtained and to study the peptides’ amino acid sequence. Identifying peptides from a complex mixture is an important component of the growing field of...

Area of Science:

  • High Energy Physics
  • Quantum Chromodynamics (QCD)
  • Standard Model of Particle Physics

Background:

  • Higgs boson production in association with a top quark and a W boson (tWH) is a key process at the Large Hadron Collider (LHC).
  • At next-to-leading order (NLO) in QCD, tWH production interferes with top quark and W boson production (tW), necessitating careful separation for precise analysis.
  • Existing techniques for handling intermediate resonances in NLO calculations, like diagram removal and subtraction, require critical evaluation in the context of tW and tWH production.

Purpose of the Study:

  • To define tWH production for both total rates and differential distributions by employing and critically assessing diagram removal and subtraction techniques.
  • To provide robust theoretical predictions for total and differential cross-sections of tW and tWH production at 13 TeV.
  • To investigate the sensitivity of tWH production to non-Standard-Model physics, specifically a relative phase between Higgs couplings to the top quark and W boson.

Main Methods:

  • Revisiting the tW production process to understand analogous interferences with t-channel single top production.
  • Applying diagram removal and subtraction techniques to define and calculate NLO QCD cross-sections for tWH and tW production.
  • Matching short-distance events to parton shower simulations and developing a reliable prescription for estimating theoretical uncertainties.

Main Results:

  • Robust predictions for total and differential cross-sections for tW and tWH production at 13 TeV are presented.
  • A reliable method for estimating theoretical uncertainties, including those related to the NLO definition of the process, has been formulated.
  • The study quantifies the sensitivity of tWH production to a potential non-Standard-Model relative phase in Higgs couplings.

Conclusions:

  • The developed techniques and robust cross-section calculations for tWH and tW production are crucial for precision measurements at the LHC.
  • The methodology provides a framework for handling interfering processes at NLO, essential for comparing theoretical predictions with experimental data.
  • The sensitivity study of tWH production to new physics offers a potential avenue for discovering physics beyond the Standard Model.
