Dark matter from encapsulated atoms
C. D. Froggatt, H. B. Nielsen
We propose that dark matter consists of collections of atoms encapsulated inside pieces of an alternative vacuum, in which the Higgs field vacuum expectation value is appreciably s…
On the smallness of the cosmological constant in SUGRA models
C. Froggatt, R. Nevzorov, H. B. Nielsen
In no--scale supergravity global symmetries protect local supersymmetry and a zero value for the cosmological constant. We consider the breakdown of these symmetries and present a…
Proceedings to the 8th Workshop 'What Comes Beyond the Standard Models', Bled, July 19. - 29., 2005, Slovenia
D. L. Bennett, M. Blagojevic, B. Cvetkovic +10
Contents: 1. Can MPP Together with Weinberg-Salam Higgs Provide Cosmological Inflation? (D.L. Bennett and H.B. Nielsen) 2. Conserved Charges in 3d Gravity With Torsion (M. Blagojev…
Crypto-baryonic Dark Matter
C. D. Froggatt, H. B. Nielsen
It is proposed that dark matter could consist of compressed collections of atoms (or metallic matter) encapsulated into, for example, 20 cm big pieces of a different phase. The ide…
Flipped SU(5), see-saw scale physics and degenerate vacua
C. R. Das, C. D. Froggatt, L. V. Laperashvili +1
We investigate the requirement of the existence of two degenerate vacua of the effective potential as a function of the Weinberg-Salam Higgs scalar field norm, as suggested by the…
Photon as a Vector Goldstone Boson: Nonlinear Model for QED
J. L. Chkareuli, C. D. Froggatt, R. N. Mohapatra +1
We show that QED in the Coulomb gauge can be considered as a low energy linear approximation of a non-linear -type model where the photon emerges as a vector Goldstone boson rel…
