Using Dimensional Reduction for Hadronic Collisions [PDF]
Nucl.Phys.B808:88-120,2009, 2008 We discuss how to apply regularization by dimensional reduction for computing hadronic cross sections at next-to-leading order. We analyze the infrared singularity structure, demonstrate that there are no problems with factorization, and show how to use dimensional reduction in conjunction with standard parton distribution functions.

Dimensional Reduction in Non-Supersymmetric Theories [PDF]
Z. Phys. C62 (1994) 161-166, 1993 It is shown that regularisation by dimensional reduction is a viable alternative to dimensional regularisation in non-supersymmetric theories.

Spontaneous Dimensional Reduction in Quantum Gravity [PDF]
, 2016 Hints from a number of different approaches to quantum gravity point to a phenomenon of "spontaneous dimensional reduction" to two spacetime dimensions near the Planck scale. I examine the physical meaning of the term "dimension" in this context, summarize the evidence for dimensional reduction, and discuss possible physical explanations.

From Topology to Generalised Dimensional Reduction [PDF]
, 1996 In the usual procedure for toroidal Kaluza-Klein reduction, all the higher-dimensional fields are taken to be independent of the coordinates on the internal space.

The dynamics of coset dimensional reduction [PDF]
Physical Review D, 2006 The evolution of multiple scalar fields in cosmology has been much studied, particularly when the potential is formed from a series of exponentials. For a certain subclass of such systems it is possible to get `assisted` behaviour, where the presence of ...

Torsion in cohomology and dimensional reduction
Journal of High Energy Physics, 2023 Conventional wisdom dictates that ℤ N factors in the integral cohomology group H p (X n , ℤ) of a compact manifold X n cannot be computed via smooth p-forms.

Quantization as a dimensional reduction phenomenon [PDF]
AIP Conference Proceedings, 2006 Classical mechanics, in the operatorial formulation of Koopman and von Neumann, can be written also in a functional form. In this form two Grassmann partners of time make their natural appearance extending in this manner time to a three dimensional ...

Gauge field corrections to 11-dimensional supergravity via dimensional reduction [PDF]
, 2017 Using the fact that eleven-dimensional supergravity yields type IIA supergravity under dimensional reduction on a circle, we determine higher-derivative terms of 11-dimensional supergravity including the $ R^4 $, $ ({\partial {F_4}})^2 R^2 $ and $ ({\partial {F_4}})^4 $ terms.

Self-completeness and spontaneous dimensional reduction [PDF]
The European Physical Journal Plus, 2013 A viable quantum theory of gravity is one of the biggest challenges facing physicists. We discuss the confluence of two highly expected features which might be instrumental in the quest of a finite and renormalizable quantum gravity -- spontaneous ...
