Bliskość i różnice tradycji chrześcijańskiego monastycyzmu Wschodu i Zachodu
One of the important platforms of the ecumenical dialogue between Eastern and Western Churches is monasticism. Despite common roots, its forms and meaning in the Church is different in the West and in the East. These differences concern mostly the role of superior, the institutional aspects of life and reference to the Church authorities. The constant exchange of texts and inspirations has always been a sign of permanent dialogue between two traditions of the same style of life. Today, the common values shared by the monks both in the West and the East, such like “spiritual fatherhood”, culture and education may become helpful not only for the ecumenical dialogue but also in the process of evangelization.Jedną z ważniejszych przestrzeni dialogu ekumenicznego między Kościołami Wschodu i Zachodu jest monastycyzm. Mimo wspólnych korzeni jego formy i znaczenie w Kościele różnią się na Wschodzie i Zachodzie. Różnice te dotyczą w większości roli przełożonego, instytucjonalnych aspektów życia i relacji z władzami kościelnymi. Stała wymiana tekstów i inspiracji zawsze była świadectwem nieustannego dialogu między dwiema tradycjami tego samego stylu życia. Dzisiaj wspólne wartości, współdzielone przez mnichów wschodnich i zachodnich, takie jak „duchowe ojcostwo”, kultura i wychowanie, mogą okazać się pomocne nie tylko w dialogu ekumenicznym, lecz i w procesie ewangelizacji

Many-body Fock sectors in Wick-Cutkosky model
In the model where two massive scalar particles interact by the ladder
exchanges of massless scalar particles (Wick-Cutkosky model), we study in
light-front dynamics the contributions of different Fock sectors (with
increasing number of exchanged particles) to full normalization integral and
electromagnetic form factor. It turns out that two-body sector always
dominates. At small coupling constant , its contribution is close
to 100%. It decreases with increase of . For maximal value
, corresponding to the zero bound state mass, two-body sector
contributes to the normalization integral 64%, whereas the three-body
contribution is 26% and the sum of all higher contributions from four- to
infinite-body sectors is 10%. Contributions to the form factor from different
Fock sectors fall off faster for asymptotically large , when the number of
particles in the Fock sectors becomes larger. So, asymptotic behavior of the
form factor is determined by the two-body Fock sector.Comment: 36 pages, 16 figure
Consistent treatment for valence and nonvalence configurations in semileptonic weak deacys
We discuss the semileptonic weak decays of ( denotes a
pseudoscalar meson). In these timelike processes, the problem of the nonvalence
contribution is solved systematically as well as the valence one. These
contributions are related to the light-front quark model (LFQM), and the
numerical results show the nonvalence contribution of the light-to-light
transition is larger than of the heavy-to-light one. In addition, the relevant
CKM matrix elements are calculated. They are consistent with the data of
Particle Data Group.Comment: 14 pages, 5 figures, revised versio
The Questionable Basis of the Common European Sales Law: The Role of an Optional Instrument in Jurisdictional Competition
Acqua e terra nei paesaggi monastici. Gestione, cura e costruzione del suolo
I testi compresi nel volume trattano del tema dell’acqua
e della terra, elementi essenziali alla vita dell’umanità,
simboli ancestrali di molte culture e al centro della Creazione
nel racconto biblico. Nelle scritture e nei testi
esegetici l’acqua è assimilata alla forza vivificante della
Parola, e come tale diviene protagonista nell’iconografia
cristiana attraverso i secoli, a partire dal medioevo.
Si indagano le funzioni svolte dai monaci benedettini
nell’organizzazione del territorio attraverso opere di
bonifica, la realizzazione di sistemi idrici, un miglioramento
nella conservazione dei frutti delle culture agricole
nelle architetture di produzione. Altri saggi esplorano
importanti aspetti della questione ambientale, al
di fuori del mondo monastico, dall’età medievale fino
ai nostri giorni, aprendosi al confronto con tradizioni
diverse, ad esempio l’uso dei terrazzamenti in Cina o
il richiamo a problemi pressanti quali quelli del rischio
idrogeologico ad Algeri o in Italia, che può compromettere
quell’armonia composta frutto di equilibrate scelte
consapevoli, oggi sempre più minacciata da una crescita
disordinata e aggressiva
Mesonic Form Factors and the Isgur-Wise Function on the Light-Front
Within the light-front framework, form factors for and
transitions (: pseudoscalar meson, : vector meson) due to the
valence-quark configuration are calculated directly in the entire physical
range of momentum transfer. The behavior of form factors in the infinite quark
mass limit are examined to see if the requirements of heavy-quark symmetry are
fulfilled. We find that the Bauer-Stech-Wirbel type of light-front wave
function fails to give a correct normalization for the Isgur-Wise function at
zero recoil in transition. Some of the form factors are found
to depend on the recoiling direction of the daughter mesons relative to their
parents. Thus, the inclusion of the non-valence configuration arising from
quark-pair creation is mandatory in order to ensure that the physical form
factors are independent of the recoiling direction. The main feature of the
non-valence contribution is discussed.Comment: 49 pages, 11 figure
