Summary
A previously disputed search channel for top quark and Higgs boson production at the Large Hadron Collider (LHC) can be observed. New methods for tagging massive Higgs bosons and top jets enable this discovery in complex environments.
Area of Science:
- High Energy Physics
- Particle Physics
- Collider Physics
Background:
- Associated production of top quarks and Higgs bosons is a key area of study at the Large Hadron Collider (LHC).
- The specific channel involving Higgs boson decay to bottom quarks has been considered unviable due to experimental challenges.
- Understanding these processes is crucial for testing the Standard Model and searching for new physics.
Purpose of the Study:
- To demonstrate a viable method for observing associated top quark and Higgs boson production.
- To overcome the limitations of previous experimental approaches for this specific decay channel.
- To develop advanced tagging techniques for massive particles in a high-background environment.
Main Methods:
- Development of specialized algorithms for tagging boosted Higgs bosons.
- Construction of sophisticated top jet taggers capable of distinguishing signal from background.
- Application of these taggers within the context of complex Quantum Chromodynamics (QCD) interactions.
Main Results:
- The proposed method successfully enables the observation of the previously disputed Higgs boson decay channel.
- The boosted Higgs and top taggers show significant performance improvements in identifying signal events.
- The study provides a concrete strategy for future experimental analyses at the LHC.
Conclusions:
- The associated production of top quarks and Higgs bosons decaying to bottom quarks is observable with advanced tagging techniques.
- The developed boosted object taggers are effective tools for exploring high-mass final states in particle physics.
- This research revives a crucial search channel, enhancing the potential for discoveries at the LHC.

01:10Detection of Black Holes
Although black holes were theoretically postulated in the 1920s, they remained outside the domain of observational astronomy until the 1970s.
Their closest cousins are neutron stars, which are composed almost entirely of neutrons packed against each other, making them extremely dense. A neutron star has the same mass as the Sun but its diameter is only a few kilometers. Therefore, the escape velocity from their surface is close to the speed of light.

03:37Subatomic Particles
Dalton was only partially correct about the particles that make up matter. All matter is composed of atoms, and atoms are composed of three smaller subatomic particles: protons, neutrons, and electrons. These three particles account for the mass and the charge of an atom.
01:06Fats as Energy Storage Molecules
Triglycerides are a form of long-term energy storage molecules. They are made of glycerol and three fatty acids. To obtain energy from fat, triglycerides must first be broken down by hydrolysis into their two principal components, fatty acids and glycerol. This process, called lipolysis, takes place in the cytoplasm. The resulting fatty acids are oxidized by β-oxidation into acetyl-CoA, which is used by the Krebs cycle. The glycerol that is released from triglycerides after lipolysis directly...
01:12Reduced Mass Coordinates: Isolated Two-body Problem
In classical mechanics, the two-body problem is one of the fundamental problems describing the motion of two interacting bodies under gravity or any other central force. When considering the motion of two bodies, one of the most important concepts is the reduced mass coordinates, a quantity that allows the two-body problem to be solved like a single-body problem. In these circumstances, it is assumed that a single body with reduced mass revolves around another body fixed in a position with an...
01:14Gravitation Between Spherically Symmetric Masses
The gravitational potential energy between two spherically symmetric bodies can be calculated from the masses and the distance between the bodies, assuming that the center of mass is concentrated at the respective centers of the bodies.
02:45Nuclear Fusion
The process of converting very light nuclei into heavier nuclei is also accompanied by the conversion of mass into large amounts of energy, a process called fusion. The principal source of energy in the sun is a net fusion reaction in which four hydrogen nuclei fuse and ultimately produce one helium nucleus and two positrons.
A helium nucleus has a mass that is 0.7% less than that of four hydrogen nuclei; this lost mass is converted into energy during the fusion. This reaction produces about...
