Quadratic electroweak corrections for polarized Moller scattering
The paper discusses the two-loop (NNLO) electroweak radiative corrections to
the parity violating electron-electron scattering asymmetry induced by squaring
one-loop diagrams. The calculations are relevant for the ultra-precise 11 GeV
MOLLER experiment planned at Jefferson Laboratory and experiments at
high-energy future electron colliders. The imaginary parts of the amplitudes
are taken into consideration consistently in both the infrared-finite and
divergent terms. The size of the obtained partial correction is significant,
which indicates a need for a complete study of the two-loop electroweak
radiative corrections in order to meet the precision goals of future
experiments
Issues and prospects of the market of mortgage loan in Latvia
LatvijÄ kopÅ” 2001.gada ir vÄrojams ÄrkÄrtÄ«gi straujÅ” izsniegto kredÄ«tu atlikuma pieaugums. PamatÄ pieaugums radies pateicoties banku agresÄ«vajai hipotekÄrajai kredÄ«tpolitikai. Å
emot vÄrÄ samÄrÄ vieglo hipotekÄro kredÄ«tu resursu pieejamÄ«bu, ir radies un vÄl joprojÄm pastÄv palielinÄts dzÄ«vojamo platÄ«bu pieprasÄ«jums, ko nenosedz tirgus piedÄvÄjums, tÄdÄjÄdi radot deficÄ«tu. TÄ rezultÄtÄ nekustamÄ Ä«paÅ”umÄ tirgÅ« jau ilgstoÅ”i ir vÄrojams ievÄrojami dinamisks cenu kÄpums. Pie Å”Ädiem apstÄkļiem pastÄv pamatotas aizdomas, ka nekustÄma Ä«paÅ”uma tirgÅ« cenas ir pÄrmÄrÄ«gi augstas un neatbilstoÅ”as normÄliem tirgus apstÄkļiem, kas raksturojas ar sabalansÄtu piedÄvÄjumu un pieprasÄ«jumu. SituÄciju saasina apstÄklis, ka LatvijÄ 2006.gada beigÄs pÄc FKTK datiem 51,8% no banku aizdevumiem ir tieÅ”i (hipotÄku kredÄ«ti, aizdevumi nekustamÄ Ä«paÅ”uma un bÅ«vniecÄ«bas nozarÄm) vai netieÅ”ie (aizdevumi citam nozarÄm nodroÅ”inÄti ar nekustÄmo Ä«paÅ”umu) saistÄ«ti ar nekustamÄ Ä«paÅ”uma tirgu un attiecÄ«gi padarot banku kredÄ«trisku Ä«paÅ”i jÅ«tÄ«gu pret nekustamÄ Ä«paÅ”uma tirgus svÄrstÄ«bÄm.
SituÄcija, kas Å”obrÄ«d izveidojusies nekustamÄ Ä«paÅ”uma tirgÅ«, rada pamatotas aizdomas, ka mainoties jebkuram no labvÄlÄ«gajiem apstÄkļiem, kas Å”obrÄ«d valda hipotekÄrÄs kreditÄÅ”anas tirgÅ«, var izraisÄ«ties krÄ«ze nekustamÄ Ä«paÅ”uma tirgÅ«, kas pakÄrtoti var apdraudÄt banku sistÄmas stabilitÄti valstÄ«.

Basically this growth appears owing to aggressive mortgage credit politics of banks. Against this background relatively easy accessibility of mortgage credits, the demand of living-space is appeared and still exists and the offer of market is not able to cover it and it makes deficit. As a result, the dynamic rise of prices is observed for a long time in the market of the fixed property. There is a reasonable suspicion that the prices in the market of the fixed property are too high and they mismatch to normal circumstances of the market which is characterized by integrated demand and offer. The situation is exacerbated by circumstance that according to the data of the Financial and Capital market Commission 51.8 % of the bank loans in Latvia at the end of 2006 are direct (mortgage credits, loans for fixed property and construction branches) or indirect (loans for other branches which are provided by fixed property) which are concerned with the market of fixed property and made the credit risk of banks specially susceptible to the fluctuations of the market of the fixed property but the rate of delivery of mortgage credits are grown up.
The situation in the market of the fixed property makes reasonable suspicions that in case of changing anyone of favorable conditions, it can generate the crisis in the market of fixed property what can endanger stability of the banks in the state dependently .
Turning out of it the research and analysis of mortgage crediting become actual with the aim to clarify what kind of problems are there and what size are them.
The credits and theoretical aspects of crediting are seen in the first chapter. The second chapter is consecrated to analysis of mortgage credits. The research results of tendencies in development of the market of mortgage credits in Latvia are arranged and affected facts of the market of mortgage credits using the data of statistics are analyzed in the third chapter.
The resolutions, conclusions, problems and suggestions for solving problems are formulated in the conclusion.

NLO electroweak radiative corrections for four-fermionic process at Belle II
We discuss the next to the leading order (NLO) electroweak radiative corrections to the eāe+ ā fāf+(Ī³) cross section asymmetry, for polarized and unpolarized beam scenario. The left-right and forward-backward amplitudes, with and without radiative corrections, are evaluated and compared for various kinematics. The hard bremsstrahlung is included for arbitrary energy cuts. The radiative corrections are shown to be significant and having a non-trivial dependency on the kinematic conditions. The calculations are relevant for the ultra-precise low-energy experiment Belle II planned at SuperKEKB
