Towards a sustainable Growth story: A critical analysis of the fundamentals
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 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 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
