Indian scientist had diiferent argument on existence of Higg's particle

An Indian scientist had made an independent argument on the existence of Higg's particle, in a manner very different from that predicted by Professor Peter Higgs.

Dr Satish D Joglekar, a professor of IIT Kanpur who passed away a few years ago, had argued in his paper in 1974 that Higg’s particle was essential for the standard model of fundamental physics.

“Joglekar had argued that if the Higg’s particle was absent then the standard model of fundamental physics would be totally unreliable beyond a certain energy scale,” says Dr Pankaj Jain, an IIT Kanpur professor who had worked with him.

The theory of elementary particles is called the Standard Model. This is the underlying model on which the whole of Physics is based on. It postulates several elementary fields which are interpreted as particles in the quantum theory. These include familiar particles such as electrons and photons, a little less familiar particles such as quarks, muons, tau leptons and neutrinos.

Quarks bind together to form protons and neutrons. Besides this it contains gluons, W and Z gauge bosons and the Higgs. The main problem with the model without Higgs is that all of these particles have zero mass.

“Joglekar however, argued the existence of Higg’s particle in a different way. In fact when I was studying a model which did not have Higg’s particle and yet managed to give masses to all the particles in the standard model, he gave me this argument that the theory will become unreliable beyond the energy scale of a few hundred GeV (Giga electron volts). This is comparable to the energy scale where LHC is probing the world of elementary particles.,” Jain said.
