WebMy interests also include cosmology, astroparticle physics, and more formal topics in quantum field theory. My current research spans a broad range of topics, including new approaches to the electroweak hierarchy problem, effective field theory for the Higgs boson, scattering amplitudes, optimal transport, and collider physics. Webthe electroweak hierarchy problem, and the strong CP problem. 1 Introduction Writing about naturalness in the current era is fraught with peril, and with good reason. Of the three major naturalness problems in high-energy physics — the cosmological con-stant problem, the electroweak hierarchy problem, and the strong CP problem — it is

Physics - Multiverse Explanation for Small Higgs Mass

WebAug 29, 2024 · Through the introduction of multiple four-form fields coupled with the Higgs scalar boson we find that both the cosmological constant and the electroweak … In theoretical physics, the hierarchy problem is the problem concerning the large discrepancy between aspects of the weak force and gravity. There is no scientific consensus on why, for example, the weak force is 10 times stronger than gravity. See more A hierarchy problem occurs when the fundamental value of some physical parameter, such as a coupling constant or a mass, in some Lagrangian is vastly different from its effective value, which is the value that gets … See more The Higgs mass In particle physics, the most important hierarchy problem is the question that asks why the weak force is 10 times as strong as gravity. Both of these forces involve constants of nature, the Fermi constant for … See more Suppose a physics model requires four parameters which allow it to produce a very high-quality working model, generating predictions of some aspect of our physical universe. Suppose we find through experiments that the parameters have values: 1.2, … See more • Naturalness • CP violation • Quantum triviality See more field rats

The Hierarchy Problem - University of Chicago

In particle physics, the electroweak interaction or electroweak force is the unified description of two of the four known fundamental interactions of nature: electromagnetism and the weak interaction. Although these two forces appear very different at everyday low energies, the theory models them as two different aspects of the same force. Above the unification energy, on the order of 246 GeV, … Webgenerate a mass hierarchy, by xing the value of the -parameter, and a pair of certain discrete pa-rameters (l= 1;s= 1). A way of solving the gauge hierarchy problem is outlined by ne-tuning the -parameter and assigning electroweak mass scales to one eld and Planck scales to the other one. In Section 6 we brie WebWeak hypercharge is the generator of the U(1) component of the electroweak gauge group, SU(2) × U(1) and its associated quantum field B mixes with the W 3 electroweak quantum field to produce the observed Z gauge boson and the photon of quantum electrodynamics.. The weak hypercharge satisfies the relation = + , where Q is the … grey tone sketchbook
