New Solutions to the Hierarchy Problem
The Standard Model (SM) is a very successful description of particle physics up to the weak scale. It agrees with all the experimental data we have our disposal today. However, it has several shortcomings. We do not know the origin of the fermion masses, which in the SM arise from the Yukawa interactions with the Higgs doublet. These are extremely varied, with a Yukawa coupling for the top of o...
متن کاملLooking for new solutions to the hierarchy problem
While in first and second quantization the fundamental operators are respectively coordinates and fields (functions), an extension of quantum field theory can be achieved if the usual pair of conjugate momenta is represented by functionals. After a brief introduction on the hierarchy problem, we show how the ordinary quantum field theory can arise from a specific limit of this extension. We wil...
متن کاملNew Solutions to the Problem of Access Control in a Hierarchy
The access control problem in a hierarchical organization consists of the management of information among a number of users who are divided into different security classes according to their suitability in accessing the information. Within the scope of cryptography the problem can be reduced to generating a cryptographic key for each security class in such a way that the key of a security class...

متن کاملLittle Higgs Models: New Approaches to the Hierarchy Problem
The experimental results of the past decade indicate that the chiral Lagrangian describing EWSB works to one loop accuracy and irrelevant operators (such as |Dω|, where ω are the Goldstone bosons eaten by W and Z) are suppressed by a scale Λ ≫ 1 TeV. This strongly indicates perturbative physics at 1 TeV and a physical Higgs boson H = (h + v)ω. However, this linear sigma model is unstable to qua...
