Radiative Breaking Scenario for the GUT gauge symmetry [PDF]
Eur.Phys.J.C46:777-781,2006, 2005 The origin of the GUT scale from the top down perspective is explored. The GUT gauge symmetry is broken by the renormalization group effects, which is an extension of the radiative electroweak symmetry breaking scenario to the GUT models. That is, in the

Gauge unification, non-local breaking, open strings [PDF]
Nucl.Phys. B730 (2005) 179-190, 2005 The issue of non-local GUT symmetry breaking is addressed in the context of open string model building. We study ZNxZM' orbifolds with all the GUT-breaking orbifold elements acting freely, as rotations accompanied by translations in the internal space.We

Renormalizable minimal SO(10) GUT in 4D and 5D [PDF]
AIP Conf.Proc.1015:3-21,2008, 2008 This report is a review of the present status of GUT, especially renormalizable minimal SO(10) GUT, and its future prospect. It consists of two parts.

Split-SUSY versus SUSY GUTS [PDF]
Prog.Theor.Phys.116:757-769,2007, 2006 The gauge coupling unification is one of main motivations in the split-SUSY scenario, and the existence of the grand unified theories (GUTs) is assumed.

Product Groups, Discrete Symmetries, and Grand Unification [PDF]
arXiv, 2002 We study grand unified theories based on an SU(5)xSU(5) gauge group in which the GUT scale, M_{GUT}, is the VEV of an exact or approximate modulus, and in which fast proton decay is avoided through a combination of a large triplet mass and small triplet ...

The gut microbiota and gut disease [PDF]
Internal Medicine Journal, 2021 AbstractThe gut microbiota has a key role in the maintenance of good health, and in the pathogenesis of gastrointestinal diseases. These conditions include the inflammatory bowel diseases, colorectal cancer, coeliac disease and metabolic liver disease. Although the nature of the microbial disturbance in these conditions has not been fully characterised,

Enterotypes of the human gut mycobiome
bioRxiv, 2022 Background The fungal component of the human gut microbiome, also known as the mycobiome, plays a vital role in intestinal ecology and human health. However, the overall structure of the gut mycobiome as well as the inter-individual variations in fungal ...

Nuclear Physics B, 2014 The structure of a Standard Model family is derived in a class of brane models with a U(M) x U(N) factor, from two mildly anthropic requirements: a massless photon and a universe that does not turn into a plasma of massless charged particles. If we choose M=3 and N=2, the only option is shown to be the Standard Model with an undetermined number of ...
