Evaluation of and
Michel Davier
This talk summarizes the recent developments in the evaluation of the leading order hadronic contributions to the running of the QED fine structure constant , at $s=M_{\rm Z}…
The Pinch Technique Beyond One Loop: The Gauge-Independent Two-Loop Quark Self-Energy
N. J. Watson
It is shown how the pinch technique algorithm may be consistently extended beyond the one-loop level to obtain the gauge-independent two-loop fermion self-energy -i\hatΣ^(2)(p) in…
A critical phenomenological study of inclusive photon production in hadronic collisions
P. Aurenche, M. Fontannaz, J. Ph. Guillet +3
We discuss fixed target and ISR inclusive photon production and attempt a comparison between theory and experiments. The dependence of the theoretical predictions on the structure…
Cosmological Phase Transitions and Radius Stabilization in Higher Dimensions
Keith R. Dienes, Emilian Dudas, Tony Gherghetta +1
Recently there has been considerable interest in field theories and string theories with large extra spacetime dimensions. In this paper, we explore the role of such extra dimensio…
Higher Order Bose-Einstein Correlations test the Gaussian Density Matrix Approach
N. Arbex, M. Pluemer, R. M. Weiner
A multiparticle system produced by a large number of independent sources is described by a gaussian density matrix W. All theoretical approach to Bose-Einstein Correlatios Cn in hi…
Charmonium Suppression in Lead-Lead Collisions: Is There a Break in the Cross-Section?
N. Armesto, A. Capella, E. G. Ferreiro
In the framework of a model based on nuclear absorption plus comover interaction, we compute the distribution of the in collisions at SPS and compare it with a…
Grand Unification at Intermediate Mass Scales through Extra Dimensions
Keith R. Dienes, Emilian Dudas, Tony Gherghetta
One of the drawbacks of conventional grand unification scenarios has been that the unification scale is too high to permit direct exploration. In this paper, we show that the unifi…
Taming the Penguin in the B0(t) -> Pi+Pi- CP-asymmetry: Observables and Minimal Theoretical Input
Jérôme Charles
Penguin contributions, being not negligible in general, can hide the information on the CKM angle alpha coming from the measurement of the time-dependent B0(t) -> pi+pi- CP-asymmet…
New Results on the Hadronic Contributions to alpha(M_Z) and to (g-2)_mu
M. Davier, A. Hocker
We reevaluate the dispersion integrals of the leading order hadronic contributions to the running of the QED fine structure constant alpha(s) at s=M_Z^2, and to the anomalous magne…
Factorization and soft-gluon divergences in isolated-photon cross sections
S. Catani, M. Fontannaz, E. Pilon
We study the production of isolated photons in annihilation and give the proof of the all-order factorization of the collinear singularities. These singularities are absor…
Reanalysis of the Das et al. sum rule and application to chiral parameters
Bachir Moussallam
A sum rule due to Das et al. is reanalyzed using a euclidian space approach and a Padé resummation procedure. It is shown that the result is essentially determined by the matrix el…
Extra Spacetime Dimensions and Unification
Keith R. Dienes, Emilian Dudas, Tony Gherghetta
We study the effects of extra spacetime dimensions at intermediate mass scales, as expected in string theories with large-radius compactifications, and focus on the gauge and Yukaw…
Medium-induced radiative energy loss; equivalence between the BDMPS and Zakharov formalisms
R. Baier, Yu. L. Dokshitzer, A. H. Mueller +1
We extend the BDMPS formalism for calculating radiative energy loss to the case when the radiated gluon carries a finite fraction of the quark momentum. Some virtual terms, previou…
Radiative Energy Loss of High Energy Partons Traversing an Expanding QCD Plasma
R. Baier, Yu. L. Dokshitzer, A. H. Mueller +1
We study analytically the medium-induced energy loss of a high energy parton passing through a finite size QCD plasma, which is expanding longitudinally according to Bjorken's mode…
The p_T Spectrum in Heavy-Flavour Hadroproduction
M. Cacciari, M. Greco, P. Nason
We consider the transverse-momentum distribution of heavy flavours in hadronic collisions. We present a formalism in which large transverse-momentum logarithms are resummed at the…
Finite Energy Chiral Sum Rules and Tau Spectral Functions
M. Davier, L. Girlanda, A. Hoecker +1
A combination of finite energy sum rule techniques and Chiral Perturbation Theory (ChPT) is used in order to exploit recent ALEPH data on the non-strange tau vector (V) and axial-v…
The Singular Behaviour of QCD Amplitudes at Two-loop Order
Stefano Catani
We discuss the structure of infrared singularities in on-shell QCD amplitudes at two-loop order. We present a general factorization formula that controls all the $\ep$-poles of the…

B0(t) -> DPP time-dependent Dalitz plots, CP-violating angles 2beta, 2beta+gamma, and discrete ambiguities
J. Charles, A. Le Yaouanc, L. Oliver +2
We study CP-violation in resonant three-body B -> DPP decays, where PP stands for either Dpi, DK_S, pipi or piK_S. Analogously to the B -> 3pi channel and the extraction of 2alpha,…
The Fading of Symmetry Non-restoration at Finite Temperature
M. B. Gavela, O. Pene, N. Rius +1
The fate of symmetries at high temperature determines the dynamics of the very early universe. It is conceivable that temperature effects favor symmetry breaking instead of restora…
