Summary
Researchers propose a method to isolate the loop-induced gluon-initiated component in associated Higgs boson production. This technique could reveal new physics at the High-Luminosity Large Hadron Collider (HL-LHC).
Area of Science:
- High Energy Physics
- Particle Physics
- Quantum Chromodynamics
Background:
- Associated Higgs boson production is crucial for understanding the Standard Model.
- The loop-induced gluon-initiated component is challenging to isolate experimentally.
- New physics beyond the Standard Model (BSM) may manifest in this component.
Purpose of the Study:
- To propose a novel method for isolating the loop-induced gluon-initiated component in associated Higgs boson production.
- To enable probing for new physics effects in this specific component at the HL-LHC.
Main Methods:
- Utilizing the similarity between the Drell-Yan-like component of Higgs boson production and the Drell-Yan process.
- Predicting the cross-section ratio of these processes with high theoretical accuracy.
Main Results:
- A method is proposed to isolate the component.
- The cross-section ratio of related processes can be accurately predicted.
- This allows for sensitive probes of new physics in the component.
Conclusions:
- The proposed method offers a promising avenue to search for new physics at the HL-LHC.
- Experimental comparison of cross-section ratios can reveal deviations from the Standard Model.
- BSM scenarios are considered to demonstrate the potential impact on the observable.

01:27Gauss's Law: Planar Symmetry
9.5K
A planar symmetry of charge density is obtained when charges are uniformly spread over a large flat surface. In planar symmetry, all points in a plane parallel to the plane of charge are identical with respect to the charges. Suppose the plane of the charge distribution is the xy-plane, and the electric field at a space point P with coordinates (x, y, z) is to be determined. Since the charge density is the same at all (x, y) - coordinates in the z = 0 plane, by symmetry, the electric field at P...

Once the fields have been calculated using Maxwell's four equations, the Lorentz force equation gives the force that the fields exert on a charged particle moving with a certain velocity. The Lorentz force equation combines the force of the electric field and of the magnetic field on the moving charge. Maxwell's equations and the Lorentz force law together encompass all the laws of electricity and magnetism. The symmetry that Maxwell introduced into his mathematical framework may not be...

01:26Gauss's Law: Spherical Symmetry
9.3K
A charge distribution has spherical symmetry if the density of charge depends only on the distance from a point in space and not on the direction. In other words, if the system is rotated, it doesn't look different. For instance, if a sphere of radius R is uniformly charged with charge density ρ0, then the distribution has spherical symmetry. On the other hand, if a sphere of radius R is charged so that the top half of the sphere has a uniform charge density ρ1 and the bottom half has a...

01:20Gauss's Law: Cylindrical Symmetry
9.4K
A charge distribution has cylindrical symmetry if the charge density depends only upon the distance from the axis of the cylinder and does not vary along the axis or with the direction about the axis. In other words, if a system varies if it is rotated around the axis or shifted along the axis, it does not have cylindrical symmetry. In real systems, we do not have infinite cylinders; however, if the cylindrical object is considerably longer than the radius from it that we are interested in,...

01:21Plastic Deformations of Members with a Single Plane of Symmetry

When a structural member undergoes plastic deformation due to bending, it is crucial to understand the position of the neutral axis and the stress distribution. This member, characterized by a single plane of symmetry, exhibits a uniform stress distribution, with negative stress above the neutral axis and positive stress below. Notably, the neutral axis does not align with the centroid of the cross-section. This misalignment is typical in cases where the cross-section is not rectangular or...
