Infinite-dimensional R-matrices for the relativistic scattering of massless modes on
Juan Miguel Nieto García, Roberto Ruiz, Alessandro Torrielli
We construct infinite-dimensional R-matrices that generalise the relativistic scattering of massless modes with the same chirality on near the Berestein-Maldacena-…
Spinning strings: -deformation and non-Abelian T-dual limit
Rafael Hernandez, Roberto Ruiz, Konstantinos Sfetsos
The simplest example of the -deformation connects the SU(2) Wess-Zumino-Witten model with the non-Abelian T-dual (NATD) of the SU(2) principal chiral model. We analyze spinning…
The Wess-Zumino-Novikov-Witten spin-chain -model
Roberto Ruiz
The Wess-Zumino-Novikov-Witten model realises bosonic-string theory in with pure Neveu-Schwarz-Neveu-Schwarz flux. We construct an ef…
Double Yang-Baxter deformation of spinning strings
Rafael Hernandez, Roberto Ruiz
We study the reduction of classical strings rotating in the deformed three-sphere truncation of the double Yang-Baxter deformation of the $\hbox{AdS}_3 \times \hbox{S}^3 \times \hb…
Quantum corrections to minimal surfaces with mixed three-form flux
Rafael Hernandez, Juan Miguel Nieto, Roberto Ruiz
We obtain the ratio of semiclassical partition functions for the extension under mixed flux of the minimal surfaces subtending a circumference and a line in Euclidean $AdS_{3}\time…
The Wess-Zumino-Witten spin chain sigma model
Rafael Hernandez, Juan Miguel Nieto, Roberto Ruiz
Classical strings propagating in supported with Neveu-Schwarz-Neveu-Schwarz flux are described by a Wess-Zumino-Witten model. In this note, we stu…
Minimal surfaces with mixed three-form flux
Rafael Hernandez, Juan Miguel Nieto, Roberto Ruiz
We study minimal area world sheets ending on two concentric circumferences on the boundary of Euclidean with mixed R-R and NS-NS three-form fluxes. We solve the problem b…
One-loop quantization of rigid spinning strings in with mixed flux
Juan Miguel Nieto, Roberto Ruiz
We compute the one-loop correction to the classical dispersion relation of rigid closed spinning strings with two equal angular momenta in the backgro…
Pulsating strings with mixed three-form flux
Rafael Hernandez, Juan Miguel Nieto, Roberto Ruiz
Circular strings pulsating in with mixed R-R and NS-NS three-form fluxes can be described by an integrable deformation of the one-dimensional Neumann-…
Prospects for natural SUSY
Jong Soo Kim, Krzysztof Rolbiecki, Roberto Ruiz +2
As we anticipate the first results of the 2016 run, we assess the discovery potential of the LHC to `natural supersymmetry'. To begin with, we explore the region of the model param…
Global analysis of the pMSSM in light of the Fermi GeV excess: prospects for the LHC Run-II and astroparticle experiments
Gianfranco Bertone, Francesca Calore, Sascha Caron +4
We present a new global fit of the 19-dimensional phenomenological Minimal Supersymmetric Standard Model (pMSSM-19) that comply with all the latest experimental results from dark m…
