Summary
Precisely measuring the top quark mass at the Large Hadron Collider (LHC) is difficult. This study introduces a new method using energy correlators for a more accurate top quark mass determination.
Area of Science:
- High-energy physics
- Particle physics
- Standard Model physics
Background:
- The top quark mass is a fundamental parameter in the Standard Model.
- Precise measurement of the top quark mass at the Large Hadron Collider (LHC) presents significant challenges.
Purpose of the Study:
- To propose a novel observable for direct access to the dimensionless quantity m_t/m_W.
- To demonstrate the feasibility of extracting the top quark mass with high precision.
Main Methods:
- Utilizing a novel energy correlator-based observable.
- Performing a Monte Carlo simulation study.
- Analyzing simulated datasets from LHC Run 2, 3, and High-Luminosity LHC.
Main Results:
- The proposed method allows for the definition of m_t in a well-controlled short-distance mass scheme.
- The observable exhibits minimal uncertainties from nonperturbative effects.
- The measurement shows insensitivity to parton distribution functions.
Conclusions:
- The developed method provides a roadmap for a record precision measurement of the top quark mass at the LHC.
- This approach offers a path to overcome current challenges in top quark mass determination.

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...

63.1K
Atoms — and the protons, neutrons, and electrons that compose them — are extremely small. For example, a carbon atom weighs less than 2 × 10−23 g. When describing the properties of tiny objects such as atoms, we use appropriately small units of measure, such as the atomic mass unit (amu). The amu was originally defined based on hydrogen, the lightest element, then later in terms of oxygen. Since 1961, it has been defined with regard to the most abundant isotope of...

01:12Atomic Number and Mass Number
13.2K
The number of protons in the nucleus of an atom is its atomic number (Z). This is the defining trait of an element. Its value determines the identity of the atom. For example, any atom that contains six protons is the element carbon and has the atomic number 6, regardless of how many neutrons or electrons it may have. A neutral atom must contain the same number of positive and negative charges, so the number of protons equals the number of electrons. This means that the atomic number also...

01:19Mass Analyzers: Common Types
717
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...

3.2K
When objects at different temperatures are placed in contact with each other but isolated from everything else, they attain thermal equilibrium. A container that prevents heat transfer in or out is called a calorimeter, and the use of a calorimeter to make measurements is called calorimetry. Generally, these measurements involve heat or specific heat capacity. The term "calorimetry problem" is used for any problem where the specified objects are thermally isolated from their...

01:22Atomic Emission Spectroscopy: Instrumentation
615
The instrumentation of atomic emission spectrometry (AES) involves various components, including atomization devices that convert samples into gas-phase atoms and ions. There are two main types of atomization devices: continuous and discrete atomizers. Continuous atomizers, like plasmas and flames, introduce samples in a constant stream, while discrete atomizers inject individual samples using syringes or autosamplers. The most common discrete atomizer is the electrothermal atomizer.
