The Hierarchy problem and new dimensions at a millimeter
- N. Arkani-Hamed, S. Dimopoulos, G. Dvali
- Physics
- 11 March 1998
Abstract We propose a new framework for solving the hierarchy problem which does not rely on either supersymmetry or technicolor. In this framework, the gravitational and gauge interactions become… Expand
Softly Broken Supersymmetry and SU(5)
- S. Dimopoulos, H. Georgi
- Physics
- 21 December 1981
We construct an explicit realistic SU(5) model in which softly broken supersymmetry is used to protect the Higgs doublets from quadratic mass renormalization. The model requires one natural but… Expand
N-flation
- S. Dimopoulos, S. Kachru, J. McGreevy, J. Wacker
- Physics
- 21 July 2005
The presence of many axion fields in four-dimensional string vacua can lead to a simple, radiatively stable realization of chaotic inflation.
New dimensions at a millimeter to a Fermi and superstrings at a TeV
- I. Antoniadis, N. Arkani-Hamed, S. Dimopoulos, G. Dvali
- Physics
- 24 April 1998
Abstract Recently, a new framework for solving the hierarchy problem has been proposed which does not rely on low energy supersymmetry or technicolor. The gravitational and gauge interactions unite… Expand
Supersymmetry and the Scale of Unification
- S. Dimopoulos, S. Raby, F. Wilczek
- Physics
- 15 September 1981
Black Holes at the LHC
- S. Dimopoulos, G. Landsberg
- Physics
- 27 June 2001
If the scale of quantum gravity is near a TeV, the LHC will be producing one black hole (BH) about every second. The BH decays into prompt, hard photons and charged leptons is a clean signature with… Expand
String Balls at the LHC and Beyond
- S. Dimopoulos, R. Emparan
- Physics
- 6 August 2001
In string theory, black holes have a minimum mass below which they transition into highly excited long and jagged strings --- ``string balls''. These are the stringy progenitors of black holes;… Expand
Black Hole Mergers and the QCD Axion at Advanced LIGO
- A. Arvanitaki, M. Baryakhtar, S. Dimopoulos, S. Dubovsky, R. Lasenby
- Physics
- 13 April 2016
In the next few years, Advanced LIGO (aLIGO) may see gravitational waves (GWs) from thousands of black hole (BH) mergers. This marks the beginning of a new precision tool for physics. Here we show… Expand
Tumbling Gauge Theories
- S. Raby, S. Dimopoulos, L. Susskind
- Physics
- 28 July 1980
We consider a class of gauge theories in which chiral fermion fields are coupled to gauge fields. If the fermion content does not form a real representation of the gauge group, these theories may… Expand
Black holes at the Large Hadron Collider.
- S. Dimopoulos, G. Landsberg
- Physics
- 27 September 2001
The very successful 2010–2012 operation of the Large Hadron Collider (LHC) has changed the landscape of particle physics. The long-awaited Higgs boson has been discovered, and—yet—there are no signs… Expand
