What does a six-dimensional figure look like? Theoretical physicist Richard Nally can’t show you exactly, but he does have a sculpture – a pink shape the size of a grapefruit – that can help you imagi...
Very effective string model?
String pattern the parameter space the triple charged black hole membrane dynamic model low energy absorption coefficient of time and space
2014/12/22
Additional evidence is presented for a recently proposed effective string model, conjectured to hold throughout the parameter space of the basic 5 dimensional, triply charged black holes, which includ...
On the boundedness of effective potentials arising from string compactifications
the boundedness of effective potentials string compactifications Mathematical Physics
2012/6/30
We study effective potentials coming from compactifications of string theory. We show that, under mild assumptions, such potentials are bounded from below in four dimensions, giving an affirmative ans...
Gauge/string duality applied to heavy ion collisions: Limitations, insights and prospects
Gauge/string duality applied to heavy ion collisions
2011/7/21
Over the last decade a fruitful interplay has developed between analyses of strongly coupled non-abelian plasmas via the gauge/string duality and the phenomenology of the quark-gluon plasma created in...
Study of $ππ$ correlations at LHC and RHIC energies in $pp$ collisions within the quark-gluon string model
quark-gluon string model RHIC energies
2011/7/21
The Quark Gluon String Model (QGSM) reproduces well the global characteristics of the $pp$ collisions at RHIC and LHC, e.g., the pseudorapidity and transverse momenta distributions at different centra...
Abstract: Assume that hadrons are formed from the emergence string. Usual string should possess two moving states: oscillation and rotation, so we propose corresponding potential and the equation of t...
Integral Equation for CFT/String Duality
Integral Equation CFT/String Duality High Energy Physics - Theory
2011/10/8
Abstract: We reinterpret and extend some old work on CFT/string duality. We consider some asymptotically conformal field theory in large N limit, with conformal symmetry broken by VEV's of infinite nu...
Nonstandard Parafermions and String Compactification
Nonstandard Parafermions String Compactification High Energy Physics - Theory
2011/9/29
Abstract: Nonstandard parafermions are built and their central charges and dimensions are calculated. We then construct new N=2 superconformal field theories by tensoring the parafermions with a free ...
The Resurgence of Instantons in String Theory
Instantons Resurgent Analysis Topological and Minimal Strings Matrix Models
2011/7/29
Abstract: Nonperturbative effects in string theory are usually associated to D-branes. In many cases it can be explicitly shown that D-brane instantons control the large-order behavior of string pertu...
Anomalous Soft Photons associated with Hadron Production in String Fragmentation
Soft Photons Hadron Production String Fragmentation
2010/12/27
The bosonized QCD2+QED2 system for quarks with two flavors contains QCD2 and QED2 bound states, with an isoscalar photon at about 25 MeV and an isovector (I=1,I_3=0) photon at about 44 MeV. Consequen...
D1-brane in Constant R-R 3-form Flux and Nambu Dynamics in String Theory
D1-brane Constant R-R 3-form Flux Nambu Dynamics String Theory
2010/12/23
We consider D1-string in a constant R-R 3-form flux background and analyze its low energy limit. The leading order low energy theory has reparametrization symmetry and is a generalization of an earli...
Aspects of the UV/IR correspondence : energy broadening and string fluctuations
the UV/IR correspondence energy broadening string fluctuations
2010/12/23
We show that a source which radiates in the vacuum of the strongly coupled N=4 SYM theory produces an energy distribution which, in the supergravity approximation, has the same space-time pattern as ...
New soliton generating transformations in the bosonic sector of heterotic string effective theory
soliton generating transformations heterotic string effective theory
2010/12/23
In the author's paper (Phys.Rev. D80, 041901(R) (2009)), the integrable structure of the symmetry reduced bosonic dynamics in the low energy heterotic string effective theory was presented. In that p...
The regular cosmic string in Born-Infeld gravity
The regular cosmic string Born-Infeld gravity
2010/12/27
It is shown that Born-Infeld gravity --a high energy deformation of Einstein gravity-- removes the singularities of a cosmic string. The respective vacuum solution results to be free of conical singul...
We study some features of the confining string connecting a quark-anti-quark pair in Yang-Mills theory. Monte Carlo investigations of the flux tube between two static quarks in the fundamental represe...
