    In this paper, I will develop an insight into the growth process of Indian Economy and will find that increased inequality due to unconventional transitions have its negative implications for future growth prospects and the overall issue of sustainability. The objective of this paper is to throw light on theoretical concepts of growth process and to suggest some policies which are in line with the conventions and at the same time are well integrated with the contemporary Indian Economy. Issues like that of consumption inequality, labor mobility etc. have been identified as inhibiting factors for a smooth flow of transitions and with a sector specific analysis, have been dealt with, so as to remove them and make the transition process free flowing, which will bring about a sustainable long-run growth strategy

    Mass Hierarchy and Vacuum Energy

    A hierarchically small weak scale does not generally coincide with enhanced symmetry, but it may still be exceptional with respect to vacuum energy. By analyzing the classical vacuum energy as a function of parameters such as the Higgs mass, we show how near-criticality, i.e. fine-tuning, corresponds universally to boundaries where the vacuum energy transitions from exactly flat to concave down. In the presence of quantum corrections, these boundary regions can easily be perturbed to become maxima of the vacuum energy. After introducing a dynamical scalar field ϕ\phi which scans the Higgs sector parameters, we propose several possible mechanisms by which this field could be localized to the maximum. One possibility is that the ϕ\phi potential has many vacua, with those near the maximum vacuum energy expanding faster during a long period of cosmic inflation and hence dominating the volume of the Universe. Alternately, we describe scenarios in which vacua near the maximum could be anthropically favored, due to selection of the late-time cosmological constant or dark matter density. Independent of these specific approaches, the physical value of the weak scale in our proposal is generated naturally and dynamically from loops of heavy states coupled to the Higgs. These states are predicted to be a loop factor heavier than in models without this mechanism, avoiding tension with experimental null results.Comment: 45 pages, 10 figures. v2: Additional discussion of inflationary cosmology scenarios, added reference
