Smooth braneworld in 6-dimensional asymptotically AdS spacetime

open access: yesJournal of High Energy Physics, 2021
In this paper, we investigate a six-dimensional smooth thick braneworld model which contains a compact extra dimension and an infinite large one. The braneworld is generated by a real scalar field with a ϕ 6 potential and the bulk is an asymptotically ...

Search for Large Extra Dimensions in Dielectron and Diphoton Production [PDF]

open access: yes, 2001
We report a search for effects of large extra spatial dimensions in ppbar collisions at a center-of-mass energy of 1.8 TeV with the DZero detector, using events containing a pair of electrons or photons.

Leptogenesis in theories with large extra dimensions [PDF]

open access: yesPhysical Review D, 1999
We study the scenario of baryogenesis through leptogenesis in higher-dimensional theories, in which the scale of quantum gravity is many orders of magnitude smaller than the usual Planck mass. The minimal realization of these theories includes an isosinglet neutrino which feels the presence of large compact dimensions, whereas all the SM particles are ...

Gauge Mediated Supersymmetry Breaking in Five Dimensions [PDF]

open access: yes, 2011
PhDIn this thesis we focus on the construction of models in which a supersymmetry breaking hidden sector is located on one fixed point of an extra dimensional interval and the effects are gauge mediated across this interval to the other fixed point ...

Activated sphalerons and large extra dimensions [PDF]

open access: yesPhysical Review D, 2002
We present a new scenario for the baryon number violation that may take place in models with large extra dimensions. Our idea is interesting because leptogenesis with a low reheating temperature requires an alternative source of the B+L violation to convert the produced leptons into baryons.

Cosmological perturbations from five-dimensional inflation

open access: yesJournal of High Energy Physics
It was recently proposed that five-dimensional inflation can relate the causal size of the observable universe to the present weakness of gravitational interactions by blowing up an extra compact dimension from the microscopic fundamental length of ...

Detecting large extra dimensions with optomechanical levitated sensors

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
Many experiments have been conducted to detect hypothetical large extra dimensions from sub-millimeter to solar system separations. However, direct evidence for such extra dimensions has not been found.

Retrospective Analysis of Donor Lymphocyte Infusions in Pediatric Patients With Mixed Chimerism After Hematopoietic Stem Cell Transplantation

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Allogeneic hematopoietic stem cell transplantation (alloHSCT) is an essential therapy for several malignant and nonmalignant diseases, but relapse and graft loss remain the principal threats to its success. Routine monitoring of chimerism and minimal residual disease (MRD) enables early detection of imminent recurrence and guides ...

Quasibound and quasinormal modes of a thick brane in Rastall gravity

open access: yesJournal of High Energy Physics
In this work, we study the gravitational quasinormal modes of the thick brane in Rastall gravity. Using the asymptotic iteration and direct integration methods, we solve the quasinormal frequencies of the Rastall thick brane.
