The standard model for the electroweak interactions is known 1,2,3,4 to contain vortex solutions that are the usual Nielsen-Olesen U(1) vortices 5 embedded in the larger electroweak symmetry group SU(2) × U(1). After briefly describing these vortex solutions, I will discuss their stability and argue that the presence of bound states can stabilize them. Then I will draw an intimate connection be...

The status of the present precision measurements of electroweak observables is reviewed with specific reference to the radiative parameters S, T, U or equivalently ǫ1, ǫ2, ǫ3. The significance of the obliqueness hypothesis is underlined and the importance of the “local fit” method of extracting these parameters from the data is emphasized. Possible new physics implications are briefly touched u...

We discuss the equation of state of neutron stars in the dense interior considering hyperons and the possible onset of kaon condensation within the relativistic mean field model. We find that hyperons are favoured in dense matter and that their appearance make the existence of a kaon condensed phase quite unlikely. Implications for the recent measurements of kaons in heavy ion collisions at sub...
