In this work, we compile the necessary and sufficient conditions a theory has to fulfill in order to ensure general lepton flavour conservation, in the spirit of the GlashowWeinberg criteria for the absence of flavour-changing neutral currents. At tree-level, interactions involving electrically neutral and doubly charged bosons are investigated. We also investigate flavour changes at 1-loop lev...

We consider the interplay of fundamental and matter-induced T violation effects in neutrino oscillations in matter. After discussing the general features of these effects we derive a simple approximate analytic expression for the T-violating probability asymmetry ∆P T ab for three-flavour neutrino oscillations in a matter with an arbitrary density profile in terms of the two-flavour neutrino am...

Fresh tomato fruit flavour is the sum of the interaction between sugars, acids, and a set of approximately 30 volatile compounds synthesized from a diverse set of precursors, including amino acids, lipids, and carotenoids. Some of these volatiles impart desirable qualities while others are negatively perceived. As a first step to identify the genes responsible for the synthesis of flavour-relat...

The mechanism where flavour symmetry of is broken spontaneously is demonstated for a model involving nonets of pseudoscalar and vector mesons. Degenerate bare nonets of vector pseudoscalar mesons coupling sufficiently strongly to each others lead to unstable self-consistency equations, such that the SU3f symmetric spectrum breaks down into a stable isospin symmetric mass spectrum similar to the...

Upper removable appliances (URA), as well as full dentures, are known to be the cause of various complaints related to oral handling of food and beverages, phonation and vocalization, in addition to general discomfort. To test the hypothesis that taste and flavour perception might also be affected by URA, 22 young orthodontic patients (10 males and 12 females aged 11.5 +/- 1.7 years; experiment...

We study flavour violation in the minimal SUSY SU(5) GUT assuming all the third generation Yukawa couplings to be due to the renormalizable physics above GUT scale. At large tan β, as suggested by Yukawa unification in SU(5), sizable flavour violation in the left (right) slepton (down squark) sector is induced due to renormalization effects of down type Yukawa couplings between GUT and Planck s...

Lipases are extensively used in the dairy industry for the hydrolysis of milk fat. The dairy industry uses lipases to modify the fatty acid chain lengths, to enhance the flavours of various cheeses. Current applications also include the acceleration of cheese ripening and the lipolysis of butter, fat and cream. The free fatty acids generated by the action of lipases on milk fat endow many dairy...

Flavour changing top decays t → cZ0, t → cg and t → cγ are predicted with invisible rates within the standard model and may represent a window on new physics. We consider these processes in supersymmetric extensions of the standard model and we show that observable rates can be obtained only if the SUSY breaking is non universal and flavour dependent.

We construct the complete and minimalO(q2) and O(q3) three-flavour Lorentz invariant chiral meson-baryon Lagrangians for the first time in the literature. We compare with previous three-flavour studies reducing the number of independent monomials and adding new ones that were missing.
