In state space search or planning, a pair of variable-value assignments that does not occur in any reachable state is considered a mutually exclusive (mutex) pair. To improve the efficiency of planners, the problem of detecting such pairs has been addressed frequently in the planning literature. No known efficient method for detecting mutex pairs is able to find all such pairs. Hence, the numbe...

With the goal of making exclusive-OR formulations of switching functions more readily available to designers for implementation in L S I and VLSI technologies, we introduce the concept of an exclusive-OR space in which an exclusive-OR normal form is deJined to correspond to the conventional disjunctive normal form. A geometrical representation of exclusive-OR space is described, and its variou...

Up to now the investigations at high energies were concentrated on inclusive processes, i.e. processes (measurements) when only one object of many produced simultaneously is recorded. Naively, these processes seem to be difficult but can be well described within the standard parton model. The exclusive processes seems naively easier, but in reality require detailed knowledge of the QCD dynamics...

We investigate the role of exclusive channels in semi-inclusive electroproduction of pions and kaons. Using the QCD factorization theorem for hard exclusive processes we evaluate the cross sections for exclusive pseudoscalar and vector meson production in terms of generalized parton distributions and meson distribution amplitudes. We investigate the uncertainties arising from the modeling of th...

We point out that hard exclusive production of tensor mesons f 2 (1270) with helicity λ = ±2 is dominated by the gluon component in the meson wave function and can be used to determine gluon admixture in tensor mesons in a theoretically clean manner. We present a detailed analysis of the tensor meson distribution amplitudes and calculate the transition form factor γ + γ * → f 2 (1270) for one r...

We use as a starting point the original, central inclusive Bialas-Landshoff model for Higgs and dijet production by a double pomeron exchange in pp (p¯ p) collisions. Next we propose the simple extension of this model to the exclusive processes. We find the extended model to be consistent with the CDF Run I, II upper limits for double diffractive exclusive dijet production. The predictions for ...

We present recent CMS measurements of diffractive and exclusive processes, using data collected at 7 TeV at theLHC. Measurements of soft singleand double-diffractive cross sections are presented, as well as measurements of photoninducedprocesses including studies of exclusive WW production via photon-photon exchange Presented at DIFFRACTION 2014 8-th International Workshop on Diffraction in Hig...

We present a review of central exclusive dijet production in p̄p collisions, where the proton and antiproton emerge intact, and only two jets of transverse energy above a certain threshold are present in the final state. The results are published in two papers by the Collider Detector at Fermilab (CDF) Collaboration, a PRL (2000) and a PRD (2008), based on data collected at √ s = 1.8 TeV and 1.9...
