Extra dimensions in superstring theory [PDF]
Nuclear Physics B, 1997 It was earlier shown that an SO(9,1) $ ^\a$ spinor variable can be constructed from RNS matter and ghost fields. $ ^\a$ has a bosonic worldsheet super-partner $ ^\a$ which plays the role of a twistor variable, satisfying $ ^ = \partial x^ +i ^ \partial $. For Type IIA superstrings, the left-moving $[ _L^\a, _L^\a]$ and right-moving $[

Natural supersymmetry from extra dimensions
Physical Review D, 2016 We show that natural supersymmetry can be embedded in a five-dimensional theory with supersymmetry breaking la Scherk-Schwarz (SS). There is no 'gluino-sucks' problem for stops localized in the four-dimensional brane and gluinos propagating in the full five-dimensional bulk, and sub-TeV stops are easily accommodated. The $ / B_ $ problem is absent

Journal of High Energy Physics, 2018 In order to localize U(1) gauge vector field on Randall-Sundrum-like braneworld model with infinite extra dimension, we propose a new kind of non-minimal coupling between the U(1) gauge field and the gravity.

Higgs Phenomenology of Minimal Universal Extra Dimensions
EPJ Web of Conferences, 2012 The minimal model of Universal Extra Dimensions (MUED) is briefly reviewed. We explain how the cross-sections for Higgs production via gluon fusion and decay into photons are modified, relative the the Standard Model (SM) values, by KK particles running ...

Thin-wall vacuum decay in the presence of a compact dimension meets the H 0 and S 8 tensions
Journal of High Energy PhysicsThe proposal of a rapid sign-switching cosmological constant in the late universe, mirroring a transition from anti-de Sitter (AdS) to de Sitter (dS) space, has significantly improved the fit to observational data and provides a compelling framework for ...

COMMUNICATION THROUGH AN EXTRA DIMENSION [PDF]
International Journal of Modern Physics A, 2000 If our visible universe is considered a trapped shell in a five-dimensional hyper-universe, all matter in it may be connected by superluminal signals traveling through the fifth dimension. Events in the shell are still causal, however, the propagation of signals proceeds at different velocities depending on the fifth coordinate.

Spinors fields in co-dimension one braneworlds
Journal of High Energy Physics, 2018 In this work we analyze the zero mode localization and resonances of 1/2−spin fermions in co-dimension one Randall-Sundrum braneworld scenarios. We consider delta-like, domain walls and deformed domain walls membranes.

Corrections to the Hawking tunneling radiation in extra dimensions
, 2015 Although the tunneling approach is fully established for black hole radiation, much work has been done to support the extension of this approach to more general settings.
