The black-disk limit in high-energy ep and pp scattering

We review a recently proposed framework for studying the approach to the unitarity limit in small-x processes in ep and pp scattering within the DGLAP approximation. Our formulation is based on the correspondence between the standard QCD factorization theorems for hard processes and the dipole picture of small-x scattering in the leading logarithmic approximation. It allows us to incorporate information about the transverse spatial distribution of gluons in the proton (GPD) from exclusive vector meson production at HERA. We show that the interaction of small-size color singlet configurations with the proton approaches the "black-disk limit" (BDL) due to the growth of the DGLAP gluon density at small x. This new dynamical regime is marginally visible in diffractive DIS at HERA, and will be fully reached in central pp collisions at LHC.Comment: 6 pages, 3 figures. Uses aipproc.cls.

Social Development, the Empowerment of Women, and the Expansion of Civil Society: Alternative Ways out of the Debt and Poverty Trap

In Pakistan’s fifty-five years, most governments have terribly neglected the overall well-being of their people. When economic growth has occurred in the past, it has been grossly inequitable. For Pakistan to escape the debt and poverty trap in which it is becoming inextricably immersed, it must prioritise social development, the empowerment of women, and the expansion of civil society over economic growth strategies. Only then can there be balanced growth—not just growth for the élites—as knowledgeable people from myriad backgrounds feel vested in Pakistan’s future. The process of globalisation has all but eliminated the possibility of a local economy being able to become competitive in the global market. Though by prioritising social development, enabling women to become full participants in the state, and expanding the power and possibilities that civil society groups can play, Pakistan will find that these are the most viable strategies to break free from the debt and poverty trap in which it finds itself today.
