Neutrinos, vacuum stability and triple Higgs coupling in SMASH
Timo J. Kärkkäinen, Katri Huitu, C. R. Das
We perform a phenomenological analysis of the observable consequences on the extended scalar sector of the SMASH (Standard Model - Axion - Seesaw - Higgs portal inflation) framewor…
SMASH-ing Vacuum Metastability
C. R. Das, Katri Huitu, Timo J. Karkkainen
Five fundamental problems - neutrino oscillations, baryogenesis, dark matter, inflation, strong CP problem - are solved at one stroke in "SM-A-S-H" (Standard Model-Axion-Seesaw-Hig…
Degenerate Vacua of the Universe and What Comes Beyond the Standard Model
B. G. Sidharth, C. R. Das, C. D. Froggatt +2
We present a new cosmological model of the Universe based on the two discoveries: 1. cosmological constant is very small, and 2. Nature shows a new law in physics called "Multiple…

C. R. Das, Jukka Maalampi, Joao Pulido +1
We investigate the prospects for determining the octant of in the future long baseline oscillation experiments. We present our results as contour plots on the ($θ_{23}-45^…
Determination of the octant in long baseline neutrino experiments within and beyond the standard model
C. R. Das, Jukka Maalampi, João Pulido +1
The recent data indicate that the neutrino mixing angle deviates from the maximal-mixing value of 45, showing two nearly degenerate solutions, one in the lower oct…
F(750), We Miss You as a Bound State of 6 Top and 6 Antitop Quarks, Multiple Point Principle
Holger F. Bech Nielsen, D. L. Bennett, C. R. Das +2
We review our speculation, that in the pure Standard Model the exchange of Higgses, including also the ones "eaten by and Z", and of gluons together make a bound state of…
New Resonances at LHC are possible. Multiple Point Principle and New Bound States in the Standard Model
L. V. Laperashvili, H. B. Nielsen, C. D. Froggatt +2
In the present paper we argue that the correction to the Higgs mass coming from the bound state of 6 top and 6 anti-top quarks, predicted early by C.D. Froggatt, H.B. Nielsen and L…
Black Holes-Hedgehogs and Strings as Defects of the Universal Vacua
B. G. Sidharth, C. R. Das, L. V. Laperashvili +1
In the present paper, assuming the Multiple Point Principle (MPP) as a new law of Nature, we considered the existence of the two degenerate vacua of the Universe: a) the first Elec…
Optimizing the octant search in long baseline neutrino experiments
C. R. Das, Jukka Maalampi, Joao Pulido +1
We study the possibility of determining the octant of the neutrino mixing angle , that is, whether or , in long baseline neutrino experi…
Topological Structure of the Vacuum, Cosmological Constant and Dark Energy
B. G. Sidharth, A. Das, C. R. Das +2
In this review we present a theory of cosmological constant and Dark Energy (DE), based on the topological structure of the vacuum. The Multiple Point Principle (MPP) is reviewed.…

In the present paper we argue that the correction to the Higgs mass coming from the bound state of 6 top and 6 anti-top quarks, predicted early by C.D. Froggatt and ourselves, lead…
False Vacuum Higgs Inflation and the Graviweak Unification
C. R. Das, L. V. Laperashvili
In the present paper we develop a model of the Higgs inflation based on the non-minimal coupling of the Higgs boson to gravity predicted by Graviweak Unification. But later we get…

It was shown: 1) that the mass of the Higgs boson discovered by LHC corresponds to the stability conditions of the SM vacua and to the Multiple Point Principle, according to which…
