Invisible Axions and Large-Radius Compactifications
Keith R. Dienes, Emilian Dudas, Tony Gherghetta
We study some of the novel effects that arise when the QCD axion is placed in the ``bulk'' of large extra spacetime dimensions. First, we find that the mass of the axion can become…
Determination of s(x) and \bar{s}(x) from a global QCD analysis
F. Zomer
A new global QCD analysis of DIS data is presented. The νFe and \barνFe differential cross-section data are included to constrain the strange component of the nucleon sea. As a res…
New Structure Function Results at Low x and High Q^2 from HERA
Zhiqing Zhang
A precise proton structure function F_2 at low x is measured. The data is interpreted in the framework of QCD with an extraction of gluon density xg. The charm contribution to F_2…
Radiative leptonic decays of B mesons in QCD
Gregory P. Korchemsky, Dan Pirjol, Tung-Mow Yan
We compute the form factors parametrizing radiative leptonic decays of heavy mesons B^+\toγe^+νfor photon energies much larger than Λ_{QCD}, where perturbative QCD methods for excl…
Finite-volume analysis of N_f-induced chiral phase transitions
Sebastien Descotes, Jan Stern
In the framework of Euclidean QCD on a torus, we study the spectrum of the Dirac operator through inverse moments of its eigenvalues, averaged over topological sets of gluonic conf…
Pionium lifetime and ππscattering lengths in generalized chiral perurbation theory
H. Sazdjian
The relationship between the pionium lifetime and the scattering lengths is established, including the sizable electromagnetic corrections. The bound state formalism that is u…
Soft High Energy Scattering in Nonperturbative QCD
E. R. Berger
In this report diffractive high energy reactions are discussed in a functional integral approach where hadronic amplitudes are calculated from vacuum expectation values of lightlik…
Single Spin Asymmetry in Heavy Flavor Photoproduction as a Test of pQCD
N. Ya. Ivanov, A. Capella, A. B. Kaidalov
We analyze in the framework of pQCD the properties of the single spin asymmetry in heavy flavor production by linearly polarized photons. At leading order, the parallel- perpendicu…
Paramagnetic effect of light quark loops on Chiral Symmetry Breaking
Sebastien Descotes, Luca Girlanda, Jan Stern
We argue that light quark loops produce a paramagnetic suppression of infrared-sensitive order parameters such as <qq>, as the number N_f of light fermions increases. The possibly…
N_f Dependence of the Quark Condensate from a Chiral Sum Rule
B. Moussallam
How fast does the quark condensate in QCD-like theories vary as a function of is inferred from real QCD using chiral perturbation theory at order one-loop. A sum rule is deri…
Evolution of average multiplicities of quark and gluon jets
A. Capella, I. M. Dremin, J. W. Gary +2
The energy evolution of average multiplicities of quark and gluon jets is studied in perturbative QCD. Higher order (3NLO) terms in the perturbative expansion of equations for the…
Asymptotic scaling of the gluon propagtor on the lattice
D. Becirevic, Ph. Boucaud, J. P. Leroy +4
We pursue the study of the high energy behaviour of the gluon propagator on the lattice in the Landau gauge in the flavorless case (n_f=0). It was shown in a precedin g paper that…
Masses and Couplings of the Lightest Higgs Bosons in the (M+1)SSM
U. Ellwanger, C. Hugonie
We study the upper limits on the mass of the lightest and second lightest CP even Higgs bosons in the (M+1)SSM, the MSSM extended by a gauge singlet. The dominant two loop contribu…
Anomaly-Induced Gauge Unification and Brane/Bulk Couplings in Gravity-Localized Theories
Keith R. Dienes, Emilian Dudas, Tony Gherghetta
It has recently been proposed that gravity-localized compactifications can generate the required gauge hierarchy without the need for hierarchically large extra spacetime dimension…
New representation for the odderon wave function
G. P. Korchemsky, J. Wosiek
New representation of the odderon wave function is derived, which is convergent in the whole impact parameter plane and provides the analytic form of the quantization condition for…
A new global analysis of deep inelastic scattering data
V. Barone, C. Pascaud, F. Zomer
A new QCD analysis of Deep Inelastic Scattering (DIS) data is presented. All available neutrino and anti-neutrino cross sections are reanalysed and included in the fit, along with…
Inclusive decay of B mesons into or
R. Aleksan, M. Zito, A. Le Yaouanc +3
We compute the inclusive decay rates including lowest order QCD corrections on the quark legs, and compare with existing data. Unlike the short distance Q…
Angular Dependence of the Radiative Gluon Spectrum and the Energy Loss of Hard Jets in QCD Media
R. Baier, Yu. L. Dokshitzer, A. H. Mueller +1
The induced momentum spectrum of soft gluons radiated from a high energy quark propagating through a QCD medium is derived in the BDMPS formalism. A calorimetric measurement for th…
Nuclear Parton Distributions - a DGLAP Analysis
K. J. Eskola, V. J. Kolhinen, P. V. Ruuskanen +1
Nuclear parton distributions are studied within a framework of the DGLAP evolution. Measurements of in deep inelastic collisions, and Drell--Yan dil…
Orsay Lectures on Confinement (III)
Vladimir Gribov
This is the third lecture on quark confinement given by V.N.Gribov in 1992 in Orsay. An extensive discussion of the consequences of all this for the structure of the Green function…
Boson Interferometry in High Energy Physics
Richard M. Weiner
Intensity interferometry and in particular that due to Bose Einstein correlations (BEC) constitutes at present the only direct experimental method for the determination of sizes an…
Baryon stopping and hyperon enhancement in the improved dual parton model
A. Capella, C. A. Salgado
We present an improved version of the dual parton model which contains a new realization of the diquark breaking mechanism of baryon stopping. We reproduce in this way the net bary…
Event-by-event fluctuations in heavy-ion collisions and the quark-gluon string model
A. Capella, E. G. Ferreiro, A. B. Kaidalov
We apply dynamical string models of heavy-ions collisions at high energies to the analysis of event-by-event fluctuations. Main attention is devoted to a new variable proposed to s…
Heavy-to-Light Form Factors in the Final Hadron Large Energy Limit of QCD
J. Charles, A. Le Yaouanc, L. Oliver +2
We argue that the Large Energy Effective Theory (LEET), originally proposed by Dugan and Grinstein, is applicable to exclusive semileptonic, radiative and rare heavy-to-light trans…
