Semi-inclusive Deep Inelastic Scattering at small x (2009)
Marquet, Cyrille, Xiao, Bo-Wen, Yuan, Feng
We study the semi-inclusive hadron production in deep inelastic scattering at small $x$. A transverse momentum dependent factorization is found consistent with the results calculated in the small-$x$...
Polarized DIS in N=4 SYM: Where is spin at strong coupling? (2009)
Hatta, Yoshitaka, Ueda, Takahiro, Xiao, Bo-Wen
Using the AdS/CFT correspondence, we calculate the polarized structure functions in strongly coupled N=4 supersymmetric Yang-Mills theory deformed in the infrared. We find that the flavor singlet...
Polarized Deep Inelastic and Elastic Scattering From Gauge/String Duality (2009)
In this paper, we investigate deep inelastic and elastic scattering on a polarized spin-1/2 hadron using gauge/string duality. This spin-1/2 hadron corresponds to a supergravity mode of the dilatino....
Deep inelastic and dipole scattering on finite length hot $\mathcal{N}=4$ SYM matter (2008)
Mueller, A. H., Shoshi, A. I., Xiao, Bo-Wen
Deep inelastic scattering of $\mathcal{R}$-currents and the scattering of a small dipole on finite length hot $\mathcal{N}=4$ SYM matter are discussed. In each case we find the scale when scattering...
Heavy-quark energy loss and thermalization in a strongly coupled SYM plasma (2008)
Beuf, Guillaume, Marquet, Cyrille, Xiao, Bo-Wen
Using the AdS/CFT correspondence, we compute the radiative energy loss of a slowly decelerating heavy quark with mass M moving through a supersymmetric Yang Mills (SYM) plasma at temperature T at...
On the exact solution of the accelerating string in $AdS_5$ space (2008)
In this letter, the exact accelerating string solution of a heavy quark-antiquark pair is found in $AdS_5$ space. On the accelerating string, there is a particular scale which separates the radiation...
Dominguez, Fabio, Marquet, C., Mueller, A. H., Wu, Bin, Xiao, Bo-Wen
We compare medium induced energy loss and $p_{\perp}$-broadening in perturbative QCD with that of the trailing string picture of SYM theory. We consider finite and infinite extent matter as well as...
On the anomalous dimensions of the multiple pomeron exchanges (2007)
High energy hard scattering in large $N_{c}$ limit can be described by the QCD dipole model. In this paper, single, double and triple BFKL pomeron exchange amplitudes are computed explicitly within...
On the behaviour of R(pA) at high energy (2007)
Kozlov, Misha, Shoshi, Arif I., Xiao, Bo-Wen
We discuss the behaviour of R(pA), the ratio of the unintegrated gluon distribution of a nucleus over the unintegrated gluon distribution of a proton scaled up by A^{1/3}, at high energy and fixed...
Fluctuation Effects on R_pA at High Energy (2007)
Kozlov, Misha, Shoshi, Arif I., Xiao, Bo-Wen
We discuss a new physical phenomenon for R_pA in the fixed coupling case, the total gluon shadowing, which arises due to the effect of gluon number fluctuations.
Space-like and time-like pion-rho transition form factors in the light-cone formalism (2007)
Yu, Jianghao, Xiao, Bo-Wen, Ma, Bo-Qiang
Having calculated the light-cone wave function of the pseudoscalar meson by using two equivalent and fully covariant methods, we generalize such methods to the valence Fock states of the vector meson...
Total gluon shadowing due to fluctuation effects (2006)
Kozlov, Misha, Shoshi, Arif I., Xiao, Bo-Wen
We show a new physical phenomenon expected for the ratio R_{pA} of the unintegrated gluon distribution of a nucleus over the unintegrated gluon distribution of a proton scaled up by the atomic factor...
On the probability distribution of the stochastic saturation scale in QCD (2006)
Marquet, C., Soyez, G., Xiao, Bo-Wen
It was recently noticed that high-energy scattering processes in QCD have a stochastic nature. An event-by-event scattering amplitude is characterised by a saturation scale which is a random...
Diffractive dissociation including pomeron loops in zero transverse dimensions (2006)
We have recently studied the QCD pomeron loop evolution equations in zero transverse dimensions [Shoshi:2005pf]. Using the techniques developed in [Shoshi:2005pf] together with the AGK cutting rules,...
Pomeron loops in zero transverse dimensions (2005)
We analyze a toy model which has a structure similar to that of the recently found QCD evolution equations, but without transverse dimensions. We develop two different but equivalent methods in order...
Multiplicity and transverse energy of produced gluon in relativistic heavy ion collision (2005)
We present a simple gluon production picture which is based on the McLerran-Venugopalan model and gluon BFKL evolution in relativistic heavy ion collision. Results for the multiplicity and transverse...

The photon-meson transition form factors of light pseudoscalar mesons $\pi ^{0}$, $\eta$, and $\eta ^{\prime}$ are systematically calculated in a light-cone framework, which is applicable as a...
Pion-photon and photon-pion transition form factors in light-cone formalism (2003)
We derive the minimal Fock-state expansions of the pion and the photon wave functions in light-cone formalism, then we calculate the pion-photon and the photon-pion transition form factors of $\gamma...
