Abstract

There are many possibilities for new physics beyond the Standard Model that feature non-standard Higgs sectors. These may introduce new sources of CP violation, and there may be mixing between multiple Higgs bosons or other new scalar bosons. Alternatively, the Higgs may be a composite state, or there may even be no Higgs at all. These non-standard Higgs scenarios have important implications for collider physics as well as for cosmology, and understanding their phenomenology is essential for a full comprehension of electroweak symmetry breaking. This report discusses the most relevant theories which go beyond the Standard Model and its minimal, CP-conserving supersymmetric extension: two-Higgs-doublet models and minimal supersymmetric models with CP violation, supersymmetric models with an extra singlet, models with extra gauge groups or Higgs triplets, Little Higgs models, models in extra dimensions, and models with technicolour or other new strong dynamics. For each of these scenarios, this report presents an introduction to the phenomenology, followed by contributions on more detailed theoretical aspects and studies of possible experimental signatures at the LHC and other colliders., Comment: Report of the CPNSH workshop, May 2004 - Dec 2005, 542 pages.

11. Search for Spatial Structures at Scales Z~1. III. The Effect of Lensing on QSO ?

Subjects
Astrophysics
Abstract

We carried out a search for peak inhomogeneities in the distribution of matter - namely clumps and voids, within the range Z ~ 1-3. We used a new method, based on the lensing of quasars by a combination of lenses, belonging to the above sought inhomogeneities in the matter distribution. This work confirms the evidence of the existence of inhomogeneities found by us earlier - of a clump (superattractor N.1), and of a void (supervoid). Besides, the existence of a new gigantic clump (superattractor N.2) was also discovered at Z ~ 3. These clumps could well serve as centers of the Bose-condensation in the early Universe; in particular - as Anselm's arion condensate, which leads to the formation of quasiperiodic structures with a period p ~ 100-200 Mpc., Comment: 22 pages, 2 figures, 6 tables. submitted to Astrophys.& Space Sci

12. Associated Production of $H^0\gamma$ or $H^0Z^0$ pairs at $\mu^+\mu^-$ Collisions

Subjects
High Energy Physics - Phenomenology
Abstract

We calculate the cross-sections for the production of Standard Model Higgs Boson in association with the neutral gauge bosons (photon and Z--boson). For the case of reaction $\mu^+ \mu^- \to \gamma H^0$, complete and compact analytical expressions for the differential and total cross--sections, applicable also for the case of any (pseudo)scalar particle with mass-coupling proportionality, in particulary, for an axion are given. Reaction $\mu^+ \mu^- \to Z^0 H^0$ is some "generalization" of the well-known "Bjorken process" for the case of $ e^+ e^-$ collisions. Various distributions for both the processes above are illustrated for the energies, which will be reached at future $\mu^+ \mu^-$ colliders. Study of those processes will be evidently complementary to the precision measurements at the Higgs resonance region., Comment: 13 pages, Latex file

Abstract

The hypothetic R--resonance production (anomalous "$l\bar l\gamma\gamma$" events at LEP) with 60 GeV mass at FNAL hadron collider has been considered. The cross-section of this R-resonance production with the consequent decay $R \to \gamma\gamma$ is obtained. Various distributions of leptons and photons in the process $p\bar p \to l\bar l R (\to \gamma\gamma) X$ are calculated., Comment: Latex, BoxedEPSF(send in the beginning of the file), 10 pages, 3 figures(available upon request for E-mail in paper), Preprint IHEP 94-69, Protvino, 1994

34. Simulation of the Neutron-Detection Efficiency and Resolution of a Scintillation Counter Based on ZnS(Ag) : 6LiF.

Author

Buchnyy, D. A., Litvin, V. S., Trunov, D. N., Marin, V. N., Axenov, S. N., and Sadykov, R. A.

Abstract

The efficiency of multilayer scintillation neutron detectors (counters) based on ZnS(Ag) : 6LiF, designed at the Institute for Nuclear Research, Russian Academy of Sciences, is analyzed by Monte Carlo simulation. The spectral dependence of the counter efficiency on the angle of incidence of the neutron beam is obtained. A series of numerical experiments is performed using the model of a time-of-flight powder diffractometer with ring detectors, based on the developed counters, with the aim of estimating its resolution. The results obtained are useful for optimizing the configuration of counters and related detecting units, while maintaining their compactness and ease of manufacture. [ABSTRACT FROM AUTHOR]

Abstract

В роботі представлено результати досліджень формування неорганічно-органічного гібриду МСМ-41 ˂PTHQ˃. Вибір матеріалу-"гостя" задовольняв умові геометричній комплементарності гостьових позицій вихідної матриці-"господаря" по відношенню до гостьового кавітандного компоненту. З метою отримання функціональної гібридності клатратної структури МСМ-41 ˂PTHQ˃ матеріал-"гість" підбирався чутливим до зовнішніх фізичних полів. В результаті синтезу було створено структуру із великою площею наногетеромеж. Дослідження електропровідності проведено методом імпедансної спектроскопії. Впровадження гостьового компоненту приводить до розщепленням домішкового енергетичного спектру, що супроводжується виникненням квантових ям. Це в свою чергу приводить до появи осциляції в середньочастотному діапазоні залежності ReZ(ω). Накладання постійного магнітного поля значним чином впливає на поведінку ReZ(ω) в середньочастотному діапазоні (відбувається дзеркальне відображення залежності). Це може свідчити про певний зсув енергетичного спектра відносно рівня Фермі постійним магнітним полем в результаті якого міняється знак асиметрії густини станів над і під рівнем Фермі. Зроблено припущення, що асиметрія густини станів відбувається саме за рахунок гостьового компоненту, і це підтверджує вигляд спектрів термостимульованого розряду (мінізонний характер з глибокими квантовими ямами). Двохдуговий вигляд діаграм Найквіста та представлена еквівалентна схема з індуктивною ланкою відображають бар'єр, який виникає на межі розділу фаз. Дія магнітного поля призводить до зростання діелектричної проникності в низькочастотному діапазоні, що в поєднанні з низьким значенням tgδ дозволяє накопичувати електричний заряд під дією магнітного поля на квантовому рівні. Знайдено умови, при яких синтезовані наногібриди можуть виявитися цікавими в якості квантових акумуляторів електричної енергії. The paper presents findings on the formation of inorganic-organic hybrid material МСМ-41 ˂PTHQ˃. The selection of a guest material proved to meet the condition of geometric complementarity of guest positions of a starting host matrix as to a guest cavitand component. The guest material appeared to be sensitive so that one could obtain the functional hybridity of the clathrate structure MCM-41˂PTHQ˃. The synthesis resulted in the formation of a structure with a large area of hetero-nano networks. The research of permittivity was conducted through the method of impedance spectroscopy. An introduction of the guest component led to the splitting of the impurity energy spectrum followed by the occurrence of quantum wells. This, in turn, gave rise to oscillations that manifested in a middle-energy region of dependences ReZ(ω). The superimposition of a constant magnetic field significantly affects the behavior of ReZ(ω) in the middle-frequency region – the dependency mirroring takes place. This may suggest a certain shift in the energy spectrum in relation to the Fermi level by the constant magnetic field, as a result of which the sign of asymmetry of the density of states changes above and below the Fermi level. An assumption has been made that the asymmetry of the density of states occurs precisely due to the guest component as clearly demonstrated by thermally stimulated discharge spectra (a miniband character of a spectrum with deep quantum wells). The two-curve Nyquist diagram and given equivalent circuit with an inductive link visualize a barrier that is observed at the phase boundary. Such an increase coupled with a low value of tgδ makes it possible to accumulate electric charge under the action of a magnetic field at a quantum level. Also, the paper demonstrates conditions under which synthesized nanohybrids could be attractive when used as quantum storage batteries.
