Dynamics of dimensional reduction

In d-dimensional unified theories that, along with gravity, contain an antisymmetric tensor field of rank s-1, preferential compactification of d-s or of s space-like dimensions is found to occur.… Expand

p-adic numbers in physics

Abstract The boundary of the ordinary open string world sheet is the real line. Along with the usual open string, one can consider p -adic open strings whose world sheet has as boundary the p -adic… Expand

Non-archimedean string dynamics

- L. Brekke, P. Freund, M. Olson, Edward Witten
- Physics
- 6 June 1988

Abstract Explicit formulas for the N-point tree amplitudes of the non-archimedean open string are derived. These amplitudes can be generated from a simple non-local lagrangian involving a single… Expand

ADELIC STRING AMPLITUDES

- P. Freund, Edward Witten
- Physics
- 17 December 1987

Abstract We show that the Veneziano and Virasoro-Shapiro four-particle scattering amplitudes can be factored in terms of an infinite product of non-archimedean string amplitudes. This factorization… Expand

A hierarchic array of integrable models

- P. Freund, A. Zabrodin
- Physics, Mathematics
- 12 August 1992

Motivated by Harish–Chandra theory, starting from a simple CDD‐pole S matrix, a hierarchy of new S matrices involving ever ‘‘higher’’ (in the sense of Barnes) gamma functions are constructed. These… Expand

Multiparticle production on hydrogen, argon, and xenon targets in a streamer chamber by 200-GeV/cproton and antiproton beams

- C. Marzo, M. Palma, +52 authors T. Spuijbroek
- Physics
- 1 September 1982

Interactions of 200-GeV protons and antiprotons on hydrogen, argon, and xenon targets were studied with a streamer-chamber vertex spectrometer at the CERN SPS. Results on multiplicities, rapidity… Expand

Macdonald polynomials from Sklyanin algebras: A conceptual basis for thep-adics-quantum group connection

- P. Freund, A. Zabrodin
- Mathematics, Physics
- 24 October 1991

We establish a previously conjectured connection betweenp-adics and quantum groups. We find in Sklyanin's two parameter elliptic quantum algebra and its generalizations, the conceptual basis for the… Expand

Topology of Higgs fields

- J. Arafune, P. Freund, C. J. Goebel
- Physics
- 1 February 1975

It is shown that the conserved magnetic charge discovered by ’t Hooft in non−Abelian gauge theories with spontaneous symmetry breaking is not associated with the invariance of the action under a… Expand

Excitation scattering in integrable models and Hall-Littlewood-Kerov polynomials

- P. Freund, A. Zabrodin
- Physics
- 24 August 1992

Abstract The S -matrices for the scattering of two excitations in the XYZ model and in all of its SU( n )-type generalizations are obtained from the asymptotic behavior of Kerov's generalized… Expand
