Summary ❶ Finite endpoint momentum strings at RHIC and LHC | Andrej Ficnar | Hard Probes 2013 Light quark energy loss from falling strings not adequate ❷ Finite endpoint momentum (shooting) strings offer better physical picture: ❸ Better match with the RHIC and LHC suppression data 2/13

❶ AdS/CFT, light quarks and energy loss

AdS/CFT in a nutshell  AdS/CFT conjecture:  Take the ‘t Hooft limit:  one can study strongly coupled gauge theories by doing classical, two-derivative (super)gravity calculations  Here: use SYM to gain insight on processes in sQGP  medium properties encoded in the metric (3+1)-dim. SYM Type IIB string theory on Maldacena, 1998 Finite endpoint momentum strings at RHIC and LHC | Andrej Ficnar | Hard Probes /13

Light quarks as falling strings (boundary) black hole D7-brane Karch & Katz, 2002 Introduce ‘quarks’: Finite temperatures: Light ‘quarks’: Finite endpoint momentum strings at RHIC and LHC | Andrej Ficnar | Hard Probes /13

Light quarks as falling strings (boundary) black hole D7-brane Finite temperatures: Light ‘quarks’: Open strings on a D7 brane = dressed pairs Chesler et al., 2009 Falling strings stopping distance Δx Finite endpoint momentum strings at RHIC and LHC | Andrej Ficnar | Hard Probes /13

Energy loss of light quarks  Maximum stopping distance in  Here: (numerically:  For and we need instantaneous energy loss  Need energy loss formalism for non-stationary strings  Susceptible to initial conditions and depends on the “jet” definition  Modified Bragg peak and numerically  Using these two we can compute  Correct shape, but a very low magnitude  jet quenching too strong  Higher derivative corrections increase it, but not enough Chesler et al., 2009 Gubser et al., 2008 Ficnar & Gubser, 2013 Chesler et al., 2009 Ficnar, 2012 Ficnar, Noronha & Gyulassy, 2012 analytically: Finite endpoint momentum strings at RHIC and LHC | Andrej Ficnar | Hard Probes /13

❷ Finite momentum at string endpoints

Finite momentum at string endpoints  Introduce finite endpoint momentum:  A more realistic description of an energetic quark:  Endpoint  quark  String  color field  Clear definition of the energy loss: energy drained from the endpoint into the bulk of the string Ficnar & Gubser, 2013 Finite endpoint momentum strings at RHIC and LHC | Andrej Ficnar | Hard Probes /13

Finite endpoint momentum - kinematics  Endpoint trajectories are null geodesics in  Maximum distance they travel is greater: “shooting strings” Finite endpoint momentum strings at RHIC and LHC | Andrej Ficnar | Hard Probes /13

Finite endpoint momentum - energy loss  A universal form of the energy loss:  Local quantity, independent of initial conditions & bulk shape of string  Independent of energy stored in the endpoint ( increases with )  Solve for (critical) null geodesics: for small for intermediate for large like pQCD collisional e-loss like pQCD radiative e-loss (only path dep.) old “AdS” e-loss Ficnar, Gubser & Gyulassy, to appear Marquet & Renk, 2010 e.g. Finite endpoint momentum strings at RHIC and LHC | Andrej Ficnar | Hard Probes /13

Conformal R AA – RHIC & LHC non-central Need better transverse expansion Finite endpoint momentum strings at RHIC and LHC | Andrej Ficnar | Hard Probes /13 in out central

GB-corrected & non-conformal R AA higher derivative (Gauss-Bonnet) corrections (  corrections)  Non-conformal (bottom-up) deformations that fit the lattice data for thermodynamics and Polyakov loops  increase energy loss at low temperatures conformal non-conformal Finite endpoint momentum strings at RHIC and LHC | Andrej Ficnar | Hard Probes /13

Conclusions & prospects

 Light quark energy loss via falling strings not adequate  Issues with initial conditions and “jet” definitions  R AA severely underpredicted  Finite endpoint momentum (shooting) strings offer better picture:  More realistic description of an energetic quark  Clear definition of energy loss  Local quantity, independent of string initial conditions  Encodes interesting physics (path dependence)  Better match with the RHIC and LHC light hadron suppression data  Prospects:  Fluctuations, better transverse expansion, non-conformal aspects  Heavy quarks  Finite corrections Finite endpoint momentum strings at RHIC and LHC | Andrej Ficnar | Hard Probes /13
