Sequential Flavour Symmetry Breaking

The gauge sector of the Standard Model (SM) exhibits a flavour symmetry which allows for independent unitary transformations of the fermion multiplets. In the SM the flavour symmetry is broken by the Yukawa couplings to the Higgs boson, and the resulting fermion masses and mixing angles show a pronounced hierarchy. In this work we connect the observed hierarchy to a sequence of intermediate eff...

Symmetry-breaking inelastic wave-mixing atomic magnetometry

The nonlinear magneto-optical rotation (NMOR) effect has prolific applications ranging from precision mapping of Earth's magnetic field to biomagnetic sensing. Studies on collisional spin relaxation effects have led to ultrahigh magnetic field sensitivities using a single-beam Λ scheme with state-of-the-art magnetic shielding/compensation techniques. However, the NMOR effect in this widely used...

Spatial symmetry breaking determines spiral wave chirality.

Chirality represents a fundamental property of spiral waves. Introducing obstacles into cardiac monolayers leads to the initiation of clockwise-rotating, counterclockwise-rotating, and pairs of spiral waves. Simulations show that the precise location of the obstacle and the pacing frequency determine spiral wave chirality. Instabilities predicted by curves relating the action potential duration...

Flavour structure , flavour symmetry and supersymmetry ∗

One of the most obscure sides of particle physics concerns the fermion flavor structure. This is a complex problem with different aspects questioning the origin of the mass spectrum and mixing pattern of quarks and leptons (including neutrinos) and CP-violation, as well as the suppression of flavor changing (FC) neutral currents, the strong CP-problem, etc. [1]. Presently, thanks to the new dat...

Gluon Condensates , Chiral Symmetry Breaking And Pion Wave - function

We consider here chiral symmetry breaking in quantum chromodynamics arising from gluon condensates in vacuum. Through coherent states of gluons simulating a mean field type of approximation, we show that the off-shell gluon condensates of vacuum generate a mass-like contribution for the quarks, giving rise to chiral symmetry breaking. We next note that spontaneous breaking of global chiral symm...
