Gravity’s Influence on the Strong Force in Protons

Introduction:

The universe we see is governed by gravity, from the movement of moons around planets to the spiral of galaxies. However, scientists are now discovering that gravity also plays a role at the smallest scales of matter.

Gravity’s Influence on Proton’s Strong Force Distribution:

Nuclear physicists at the Thomas Jefferson National Accelerator Facility (Jefferson Lab) have used a method that connects theories of gravitation to interactions among the smallest particles of matter to reveal new details at this smaller scale.

Unveiling the Strong Force Distribution in Protons:

For the first time, a snapshot of the strong force distribution inside the proton has been obtained. This snapshot reveals the shear stress the force may exert on the quark particles that make up the proton.

Insights into the Proton’s Environment:

The measurement provides insights into the environment experienced by the proton’s building blocks, the quarks, which are bound together by the strong force.

Measuring the Proton’s Mechanical Properties:

The result is only the second of the proton’s mechanical properties to be measured, including its internal pressure, mass distribution, angular momentum, and shear stress.

Connecting Gravity to Subatomic Interactions:

The result was made possible by a half-century-old prediction and two-decade-old data, connecting how gravity interacts with subatomic particles, such as the proton, to reveal the proton’s mechanical properties directly.

Deeply Virtual Compton Scattering (DVCS):

A specific process called deeply virtual Compton scattering (DVCS) was found to be connected to how gravity interacts with matter, allowing scientists to extract information about the proton’s mechanical properties.

Future Research Directions:

Researchers aim to extract more information from existing DVCS data to determine the proton’s mechanical size and take advantage of newer experiments continuing the DVCS research in the proton.

Impact on Theoretical Research:

The study has sparked a surge of theoretical efforts, with hundreds of publications exploring this newly discovered avenue for studying the proton’s mechanical properties.

Changing Perspectives on Proton Structure:

The research has changed the way scientists think about the structure of the proton, expressing it in terms of forces, pressure, and physical sizes that non-physicists can relate to.

Wrapping Up:

The discovery of gravity’s influence on the strong force in protons opens up new avenues for understanding the fundamental forces that shape our universe, both at the largest and smallest scales. As research continues, we can expect to uncover more insights into the intricate workings of the subatomic world.

Strong interaction
In nuclear physics and particle physics, the strong interaction, also called the strong force or strong nuclear force, is a fundamental interaction that confines quarks into protons, neutrons, and other hadron particles. The strong interaction also binds neutrons and protons to create atomic nuclei, where it is called the nuclear...
