Behaviour (e.g., real-time dynamics) of strongly-coupled QCD plasma is of interest for RHIC and early universe cosmology Theoretical tools to study such strongly-coupled systems are very limited (e.g., nonexistent)

Behaviour (e.g., real-time dynamics) of strongly-coupled QCD plasma is of interest for RHIC and early universe cosmology Theoretical tools to study such strongly-coupled systems are very limited (e.g., nonexistent) AdS/CFT correspondence provides simple tools to study some strongly-coupled guage theories, e.g., Type IIb strings on AdS 5 X S 5 with RR flux N C D=4 N =4 U(N C ) super-Yang-Mills limited to: large N C and large ’t Hooft coupling sugra

QCD N =4 SYM confinement, discrete spectrum, scattering,.... conformal, continuous spectrum, no S-matrix, SUSY,.... very different !!

T>T C T>>T C very similar !! runs to weak coupling remains strongly-coupled very different !!

Reality check? Is this more than hot air? Karsch (hep-lat/ )

T/T c ε/ε0ε/ε0 N=4 SYM (Gubser, Klebanov & Peet hep-th/ ) scale energy density by free result Reality check? Is this more than hot air? Karsch (hep-lat/ )

RHIC ε/ε0ε/ε0 N=4 SYM scale energy density by free result “80% is closer to 75% than 100%” Strongly coupled QGP seems to be “conformal”, just above T c LHC T/T c

AdS/CFT : RHIC data : small Consider shear viscosity: (Kovtun, Son & Starinets hep-th/ ; hep-th/ ) (Romatschke & Romatschke arXiv: ; Song & Heinz arXiv: ; ) AdS/CFT does not give identical physics to QCD, but may indicate universal behaviour, applicable to sQGP Present exploration towards adding “fundamental” matter

Field theory story: N =2 SU(N c ) super-Yang-Mills with (N f +1) hypermultiplets N f massive hyper’s “quarks” 2 complex scalars : 2 Weyl fermions: N =4 SYM content fund. in U(N c ) & global U(N f ) (Reader’s Digest version) fundamental adjoint adjoint fields: vector: 1 hyper: fundamental fields: work in limit of large N c and large λ but N f fixed “quenched approximation”:

low temperatures: free quarks mesons ( bound states) Finite Temperature: phase transition: high temperatures: NO quark or meson quasi-particles “quarks dissolved in strongly coupled plasma” (strong coupling!!) note not a confining theory: free quarks “mesons” ( bound states) unusual dispersion relations: quasi-particle widths increase dramatically near

add N f probe D7-branes horizon AdS 5 boundary pole equator S5S5 S3S3 D7 Free quarks appear with mass: Karch & Katz (hep-th/ ) Adding flavour to AdS/CFT Aharony, Fayyazuddin & Maldacena (hep-th/ )

add N f probe D7-branes horizon AdS 5 boundary pole equator S5S5 S3S3 D7 Karch & Katz (hep-th/ ) Adding flavour to AdS/CFT Mesons ( bound states) dual to open string states supported by D7-brane Aharony, Fayyazuddin & Maldacena (hep-th/ )

Mesons: lowest lying open string states are excitations of the massless modes on D7-brane: vector, scalars (& spinors) (free) spectrum: expand worldvolume action to second order in fluctuations solve linearized eq’s of motion by separation of variables V eff r Discrete spectrum: Kruczenski, Mateos, RCM & Winters [hep-th/ ] = radial AdS # = angular # on S 3

Gauge theory thermodynamics = Black hole thermodynamics Gauge/Gravity thermodynamics: Witten (hep-th/ ); ….. Replace SUSY D3-throat with throat of black D3-brane Wick rotate and use euclidean path integral techniqes..... Extend these ideas to include contributions of probe branes/fundamental matter

Gauge/Gravity thermodynamics with probe branes: put D7-probe in throat geometry of black D3-brane SUSY embedding Minkowski embedding Black hole embedding T=0: “brane flat” Low T: tension supports brane; D7 remains outside BH horizon raise T: horizon expands and increased gravity pulls brane towards BH horizon High T: gravity overcomes tension; D7 falls through BH horizon D7 D3 Phase transition † ( † This new phase transition is not a deconfinement transition.) Mateos, RCM &Thomson [hep-th/ ];..... Babington, Erdmenger, Evans, Guralnik & Kirsch [hep-th/ ]

Mesons in Motion: pseudoscalar scalar Mateos, RCM &Thomson [hep-th/ ] Ejaz, Faulkner, Liu, Rajagopal & Wiedemann [arXiv: ] Radial profile k increasing

holographic model shows bound states persist above T c and have interesting dispersion relation lattice QCD indicates heavy quark bound states persist above T c Asakawa & Hatsuda [hep-lat/ ] Datta, Karsch, Petreczky & Wetzorke [hep-lat/ ] Satz [hep-ph/ ] ’s have finite width! but in Mink. phase, holographic mesons are absolutely stable (for large N c ) can we do better in AdS/CFT?

Spectral functions: diagnostic for “meson dissociation” simple poles in retarded correlator: yield peaks: “quasi-particle” if characteristic high “frequency” tail:

discrete spectrum; low temperature Mink. phase continuous spectrum; high temperature BH phase mesons stable (at large N c ) no quasi-particles hi-freq tail Spectral functions: diagnostic for “meson dissociation”

Kobayashi, Mateos, Matsuura, RCM & Thomson [hep-th/ ] Mateos, Matsuura, RCM & Thomson [arXiv: ];..... Need an extra dial: “Quark” density D7-brane gauge field: asymptotically (ρ→∞):

Kobayashi, Mateos, Matsuura, RCM & Thomson [hep-th/ ] Mateos, Matsuura, RCM & Thomson [arXiv: ];..... Need an extra dial: “Quark” density electric field lines can’t end in empty space; n q produces neck D7-brane gauge field: asymptotically (ρ→∞): BH embedding with tunable horizon

See also: Erdmenger, Kaminski & Rust [arXiv: ] Increasing n q, increases width of meson states Spectral functions: n q = 0 = 0.06 = 0.15 = 0.25 at rest: q=0

Spectral functions: introduce nonvanishing momentum (n q = 0.25)

Spectral functions: follow positions of peaks real part of quasiparticle frequency, Ω(q) (n q = 0.25)

Spectral functions: follow positions of peaks real part of quasiparticle frequency, Ω(q) (n q = 0.25) v lim = (calculated for n q =0) Quasiparticles obey same speed limit!

follow widths of peaks imaginary part of quasiparticle frequency, Γ(q) v lim =.995 =.651 =.343 =.651

examine Schrodinger potential for quasinormal modes

Quasiparticles limited to maximum momentum q max (define q max as value where V eff has inflection point) continuous curves fit with form: n q = = = 0.25

Conclusions/Outlook: first order phase transition appears as universal feature of holographic theories with fundamental matter (T f > T c ) how robust is this transition? D3/D7 system: interesting framework to study quark/meson contributions to strongly-coupled nonAbelian plasma “speed limit” universal for holographic theories quasiparticle widths increase dramatically with momentum more analytic control; quasinormal spectrum find in present holographic model universal behaviour? real world effect? ( INVESTIGATING) extended excitations? QCD??
