1 HoravaWitten Cosmology
, 2003
"... We consider the cosmology of the reduced 5D HoravaWitten MTheory (HW) with volume modulus and treating matter on the orbifold planes to first order. It is seen that one can recover the FRW cosmology in the Hubble expansion era with relativistic matter, but if a solution exist with nonrelativistic ..."

COSMOLOGY IN HORAVAWITTEN MTHEORY
, 2002
"... The cosmology of the HoravaWitten MTheory reduced to five dimensions retaining the volume modulus is considered. Brane matter is considered as a perturbation on the vacuum solution, and the question of under what circumstances does the theory give rise to the standard RWF cosmology is examined. It ..."

Five Dimensional Cosmology in HoravaWitten MTheory
, 2004
"... The cosmology in the Hubble expansion era of the HoravaWitten Mtheory compactified on a CalabiYau threefold is studied in the reduction to fivedimensions where the effects of the CalabiYau manifold are summarized by the volume modulus, and all perturbative potentials are included. Matter on the ..."

, 2000
"... The general structure of the matter Kahler metric in the κ 2/3 expansion of HoravaWitten Mtheory with nonstandard embeddings is examined. It is shown that phenomenological models based on this structure can lead to Yukawa and VCKM hierarchies (consistent with all data) without introducing ad hoc s ..."

The Cosmological Constant in CalabiYau 3fold Compactifications of the HoravaWitten Theory
, 2000
"... Brane world scenarios offer a way of setting the cosmological constant to zero after supersymmetry breaking provided there is a sufficient number of adjustable integration constants/parameters. In the case of the HoravaWitten theory compactified on a CalabiYau threefold, we argue that it is diffic ..."

QUARK, LEPTON AND NEUTRINO MASSES IN HORAVAWITTEN INSPIRED MODELS
, 2002
"... HoravaWitten MTheory offers new ways in achieving the quark and lepton mass hierarchies not naturally available in supergravity unified models. In previous work, based on a torus fibered CalabiYau manifold with a del Pezzo base dP7,a three generation SU(5)model with Wilson line breaking to the St ..."

LTH–746 On the Low Energy Spectra of the Nonsupersymmetric Heterotic String Theories
, 706
"... The ten dimensional string theories as well as eleven dimensional supergravity are conjectured to arise as limits of a more basic theory, traditionally dubbed M–theory. This notion is confined to the ten dimensional supersymmetric theories. String theory, however, also contains ten dimensional non– ..."

– supersymmetric theories that have not been incorporated into this picture. In this note we explore the possibility of generating the low energy spectra of various nonsupersymmetric heterotic string vacua from the Horava–Witten model. We argue that this can be achieved by imposing on the Horava–Witten model
Gravity coupling from microblack holes
, 2000
"... Recently much work has been done in lowering the Planck threshold of quantum gravitational effects (submillimeter dimension(s), HoravaWitten fifth dimension, strings or branes low energy effects, etc.). Working in the framework of 4dim gravity, with semiclassical considerations based on Hawking ..."

hepth/9804096 Cosmological Solution in Mtheory on S 1 /Z2
, 1998
"... We provide the first example of a cosmological solution of the HoravaWitten supergravity. This solution is obtained by exchanging the role of time with the radial coordinate of the transverse space to the fivebrane soliton. On the boundary this corresponds to rotating an instanton solution into a ..."
