	Parton and Hadron Production in e+e- Annihilation (1980)
		The processes of hadron formation are taken to be sensitive only to the probabilities, and not the amplitudes, for the possible configurations of the parton system.
		If the formation of hadrons does not occur in some such local and universal manner, there seems little hope of obtaining useful predictions from QCD without very detailed knowledge of the structure of hadrons.
		In addition to single hadron inclusive spectra, fragmentation functions may also be used to describe multihadron spectra [12,13].

	LHPC
		The Lattice Hadron Physics Collaboration (LHPC) is a collaboration of scientists interested in first-principles calculations of hadron structure through lattice gauge theory calculations.
		Lattice calculations are essential to extract physics from major experimental studies of hadron structure
		A further crucial component of our work is an understanding of lattice field theory, including, for example, the development of efficient computational algorithms.

	LHPC: Hadron-Hadron Interaction
		Since we do not yet understand the internal structure of an isolated hadron from first principles, it is clear that we cannot presently have a fundamental, quantitative theory of the interactions between hadrons.
		Hence, as in the case of hadron structure, there is an increasing appreciation of the need to understand hadronic interactions in terms of the underlying field theory, QCD, and recognition that lattice QCD and computing resources have advanced to the point that one can hope to obtain genuine insight from ab initio lattice calculations.
		We believe that the study of interactions of hadrons containing heavy quarks will provide physical insight into the nature of the nucleon-nucleon force, and is an essential precursor to the application of lattice QCD to multi-hadron systems.

	Hadron Summary
		Hadrons are subatomic particles that are affected by the strong force, the force that binds the nucleus together.
		Hadrons are combinations of basic particles, quarks and gluons, held together by the strong force.
		All hadrons are single particle excitations of the basic theory of strong interactions, called quantum chromodynamics.

		Hadron is looking for companies in the $10 million to $20 million range that offer services in areas like software and hardware development, trusted and secure computer systems and intelligent weapons systems, company officials said.
		Accounting firm Coopers and Lybrand LLP, which was auditing Hadron in fall 1995, noted that the company had a net capital deficiency and losses from operations so that it doubted whether it could continue as a going concern, according to Hadron's annual report.
		Hadron executives blamed government budget constraints as well as the cost of keeping technical workers on staff, even when there isn't work for them.

	Dr. Winston Roberts, Hadron Physics
		One can draw a spectrum of 'lines' representing the excited states of hadrons, but unlike the spectrum of hydrogen, or any other atom, this spectrum would not have a 'maximum' energy like the hydrogen spectrum, but the energies of the states would keep rising, perhaps forever.
		For instance, many of the states in the nucleon spectrum shown would have transitions to the ground state nucleon with the emission of a meson, such as a pion (&pi) or eta (&eta), or even a rho (&rho), which is an excited version of the pion.
		Hadron physicists are working to understand how confinement comes about, and how it generates the mass of the nucleon.

	CERN Itanium system powers large Hadron collider
		A LARGE Hadron Collider that has a circumference of 27 kilometres and to start operations in 2007 is being designed and tested using an Itanium 2 cluster, Intel said.
		The Large Hadron Collider grid will have to distribute data at 1,500MB a second over a decade, with the raw bits and bits being analysed at 150 computing centres worldwide.
		The data during one year of operation of the large Hadron cluster will exceed 15 Petabytes - which Intel reckons is one per cent of the worldwide production of information today in digital and non digital forms.

	Exploration of Hadron Structure and Spectroscopy using Lattice QCD (06-1)
		As a result of developments in lattice field theory and computer technology and of the investment by the DOE in lattice QCD facilities for the national community, the first full QCD calculations in the chiral regime are becoming available, opening a new era for confronting experiment with solutions of QCD from first principles.
		Hence, the goal of this program is to bring together theorists from all the areas whose coordinated efforts are required to exploit these new opportunities, including chiral perturbation theory, perturbative and nonperturbative renormalization, numerical lattice calculations, and thoughtful phenomenology.
		The focus will be twofold, both using lattice QCD to obtain insight into hadron structure and spectroscopy, and calculating observables that are relevant to current experiments and that will guide the future experimental program.

	hadron structure (Site not responding. Last check: )
		Understanding the structure of hadrons is one of the great unsolved problems in physics, and as such is the subject of both theoretical and experimental effort at MIT.
		Robert Jaffe and his collaborators developed the MIT bag model of confinement, still one of the favorite models of quark dynamics, and applied it to the spectrum and structure of hadrons.
		Recently, he and Frank Wilczek have proposed a model for the newly discovered pentaquark baryons, suggesting that they are best thought of as two diquarks and one antiquark.
