متن کاملLatest results from lattice QCD for the Roper resonance
In the excited baryon spectrum, of particular interest is the level order of the positive-parity excited nucleon, so-called the Roper resonance N (1440) and the negative-parity nucleon N(1535). It is worth mentioning that this pattern of the level order between positive and negative-parity excited states can be found universally in the ∆, Σ and flavor-octet Λ channels. It is also interesting to...
متن کاملData Envelopment Analysis from simulation on the Lattice QCD using CCR model
One of the most serious principles in production theory in economic is the principle of "efficiency". Simply put, efficiency can be defined as the demand that the desired goals (outputs) are achieved with the minimum use of the available resources (inputs). In order to, distinguish the relative efficiency of organizational units with multiple inputs to produce multiple outputs, "Data Envelopmen...

متن کاملPhenomenology from lattice QCD ∗
The lattice formulation of quantum field theory, combined with large scale numerical simulations, is contributing in a variety of ways to the current research effort in particle physics. In the present talk I will focus on lattice QCD and its rôle in quantifying non-perturbative strong interaction effects. I wish to apologize straight away to those colleagues whose work I will not be able to co...
