Additional Subnuclear Structures

Additional Subnuclear Structures

The eukaryotic nucleus is a double membrane-bound organelle that contains nearly all of the cell’s genetic material in the form of chromosomes. It is rightly called the “brain” of the cell as it shoulders the responsibility of responding to various physiological processes, stress, altered metabolic conditions, and other cellular signals.
The nucleus contains many membrane-less subnuclear organelles or nuclear bodies, such as nucleoli, Cajal bodies, speckles, paraspeckles, etc. These nuclear...

Atomic Absorption Spectroscopy: Atomization Methods

Atomic Absorption Spectroscopy: Atomization Methods

Atomic Absorption Spectroscopy (AAS) atomizes samples through flame atomization or electrothermal atomization. Flame atomization typically involves a nebulizer and spray chamber assembly to combine the sample with a fuel–oxidant mixture, creating a fine aerosol mist that enters a burner. Typically, the fuel and oxidant are combined in an approximately stoichiometric ratio. However, for atoms that are easily oxidized, a fuel-rich mixture may be more advantageous. Only about 5% of the aerosol...

Equilibrium Conditions for a Particle

Equilibrium Conditions for a Particle

When an object is in equilibrium, it is either at rest or moving with a constant velocity. There are two types of equilibrium: static and dynamic. Static equilibrium occurs when an object is at rest, while dynamic equilibrium occurs when an object is moving with a constant velocity. In both cases, there must be a balance of forces acting on the object.
To understand the concept of equilibrium, let us first consider the forces acting on an object. When different forces act on an object, they can...

The Quantum-Mechanical Model of an Atom

The Quantum-Mechanical Model of an Atom

Shortly after de Broglie published his ideas that the electron in a hydrogen atom could be better thought of as being a circular standing wave instead of a particle moving in quantized circular orbits, Erwin Schrödinger extended de Broglie’s work by deriving what is now known as the Schrödinger equation. When Schrödinger applied his equation to hydrogen-like atoms, he was able to reproduce Bohr’s expression for the energy and, thus, the Rydberg formula governing hydrogen spectra. Schrödinger...

Atomic Nuclei: Nuclear Relaxation Processes

Atomic Nuclei: Nuclear Relaxation Processes

In the absence of an external magnetic field, nuclear spin states are degenerate and randomly oriented. When a magnetic field is applied, the spins begin to precess and orient themselves along (lower energy) or against (higher energy) the direction of the field. At equilibrium, a slight excess population of spins exists in the lower energy state. Because the direction of the magnetic field is fixed as the z-axis, the precessing magnetic moments are randomly oriented around the z-axis. This...

Summary

This summary is machine-generated.

We present a new method in jet physics, accurately predicting energy profiles and invariant mass distributions for light-quark and gluon jets using perturbative quantum chromodynamics (pQCD). Our findings align well with experimental data from the Tevatron and Large Hadron Collider.

Area of Science:

High-energy particle physics
Quantum chromodynamics (QCD)

Background:

Understanding the behavior of jets produced in high-energy particle collisions is crucial for testing fundamental theories.
Jets originating from light quarks and gluons are prevalent but theoretically challenging to model accurately.

Purpose of the Study:

To develop a novel theoretical framework for predicting the energy profiles and invariant mass distributions of light-quark and gluon jets.
To improve the precision of theoretical predictions in perturbative quantum chromodynamics (pQCD).

Main Methods:

Employing a resummation formalism to all orders in the coupling constant within perturbative QCD.
Applying the developed formalism to calculate energy profiles and invariant mass distributions of jets.

Main Results:

The theoretical predictions for energy profiles show excellent agreement with experimental data from the Tevatron (CDF) and Large Hadron Collider (CMS).
The extended formalism accurately reproduces the peak positions and heights in jet invariant mass distributions, consistent with CDF data.

Conclusions:

The developed resummation technique provides a significant advancement in jet physics, offering accurate predictions for light-quark and gluon jets.
This work validates the applicability of perturbative QCD calculations for describing complex jet properties in experimental observables.
