Summary
Asymptotic safety in supersymmetric gauge theories is explained, revealing enhanced predictivity due to supersymmetry. This study identifies superconformal fixed points and UV-IR trajectories for these theories.
Area of Science:
- Quantum Field Theory
- High Energy Physics
- String Theory
Background:
- Asymptotic safety is a proposed mechanism for a UV-complete quantum field theory.
- Supersymmetric gauge theories are important in physics beyond the Standard Model.
Purpose of the Study:
- To explain the emergence of asymptotic safety in four-dimensional supersymmetric gauge theories.
- To provide concrete examples of asymptotically safe supersymmetric gauge theories.
Main Methods:
- Investigation of supersymmetric gauge theories in a Veneziano limit for perturbative control.
- Analysis of superconformal fixed points, R charges, and phase diagrams.
- Establishment of consistency with unitarity and the a theorem.
Main Results:
- Identification of asymptotically safe supersymmetric gauge theories with superconformal fixed points.
- Determination of R charges and UV-IR connecting trajectories.
- Demonstration that supersymmetry enhances the predictivity of asymptotically safe theories.

03:18Nuclear Stability
23.4K
Protons and neutrons, collectively called nucleons, are packed together tightly in a nucleus. With a radius of about 10−15 meters, a nucleus is quite small compared to the radius of the entire atom, which is about 10−10 meters. Nuclei are extremely dense compared to bulk matter, averaging 1.8 × 1014 grams per cubic centimeter. If the earth’s density were equal to the average nuclear density, the earth’s radius would be only about 200 meters.

01:16Conservation of Mass in Finite Cotrol Volume
1.8K
The principle of conservation of mass is a fundamental law in fluid mechanics and is applied using the continuity equation. We apply the concept to a finite control volume to derive the continuity equation.
A system is defined as a collection of unchanging contents, and the conservation of mass states that a system's mass is constant.

01:14Stability of structures
534
In mechanical engineering, the stability of systems under various forces is critical for designing durable and efficient structures. One fundamental way to explore these concepts is by analyzing systems like two rods connected at a pivot point, O, with a torsional spring of spring constant k at the pivot point. This system is similar in appearance to a scissor jack used to change tires on a car. In this case, the arms of the linkage (equivalent to the rods in this system) are entirely vertical,...

01:23Stability of Equilibrium Configuration
824
Understanding the stability of equilibrium configurations is a fundamental part of mechanical engineering. In any system, there are three distinct types of equilibrium: stable, neutral, and unstable.
A stable equilibrium occurs when a system tends to return to its original position when given a small displacement, and the potential energy is at its minimum. An example of a stable equilibrium is when a cantilever beam is fixed at one end and a weight is attached to the other end. If the weight...

01:14Norton's Theorem
1.5K
Norton's theorem is a fundamental principle stating that a linear two-terminal circuit can be substituted with an equivalent circuit, which comprises a current source (ⅠN) in parallel with a resistor (RN). Here, ⅠN represents the short-circuit current flowing through the terminals, and RN stands for the input or equivalent resistance at the terminals when all independent sources are deactivated. This implies that the circuit illustrated in Figure (a) can be exchanged with the one depicted...

01:18Superposition Theorem
1.5K
The superposition principle is a fundamental concept stating that in a linear circuit, the voltage across (or current through) an element can be determined by summing the individual contributions of each independent source acting in isolation. When dealing with linear circuits containing multiple independent sources, this principle serves as a valuable tool for analysis. To apply the superposition principle effectively, one should focus on a single independent source at a time while...
