Using the gravitational mass spectroscopy (GMS) of water cluster ensembles in agarose hydrogel the center of the Milky Way (CMW) was scanned during the opposition of the Sun and CMW in summer 2014. The radiation of axions and neutrinos from CMW was found to influence the long-range order in water of hydrogel. It was observed that the dimensions of CMW were not stable and changed in a wide diapason; the smallest core size amounted to 3.6 11 km (0.3'' flat angle). In the gravitational noises (GN) of water cluster ensembles, resonance processes reflecting events in CMW were recorded. While a broad spectrum of neutrinos was emitted by CMW for axions, the number of signals, though very strong, was limited. The flows of these elementary particles (EP) from CMW and Sun formed stationary shock waves between the two, which was visually registered in the earth atmosphere. CMW was not homogeneously a plurality of mass concentrations (clusters) moving with high velocity into GMW and generating EP were observed. The bar formation in CMW was modeled. A model of the Black hole in CMW as an ensemble of neutron stars' clusters was discussed. [ABSTRACT FROM AUTHOR]

We introduce a C++ header-only library that is used to solve the axion equation of motion, MiMeS. MiMeS makes no assumptions regarding the cosmology and the mass of the axion, which allows the user to consider various cosmological scenarios and axion-like models. MiMeS also includes a convenient python interface that allows the library to be called without writing any code in C++, with minimal overhead. Program title: MiMeS CPC Library link to program files: https://doi.org/10.17632/8ttm4snpzj.1 Developer's repository link: https://github.com/dkaramit/MiMeS Programming language: C++ and python Licensing provisions: MIT license Nature of problem: Solving numerically the axion (or axion-like-particle) equation of motion, in order to determine the corresponding relic abundance. The library is designed to be quite general, and can be used to obtain the relic abundance in various cosmological scenarios, and axion-like-particle models. Solution method: Embedded Runge-Kutta for the numerical integration of the equation of motion. The user may choose between explicit and Rosenborck methods, or implement their own Butcher tableau. For the various interpolations, the library uses cubic splines. Additional comments including restrictions and unusual features: The derivative of the axion-angle initially is assumed vanish. This is hard-coded in the library, and there is no easy way for the user to change it. Furthermore, any additional contribution from decays or annihilation of plasma particles to the axion (or ALP) energy density is assumed to be subdominant. [ABSTRACT FROM AUTHOR]

The REST-for-Physics (Rare Event Searches Toolkit for Physics) framework is a ROOT-based solution providing the means to process and analyze experimental or Monte Carlo event data. Special care has been taken to the traceability of the code and the validation of the results produced within the framework, together with the connectivity between code and stored data, registered through specific version metadata members. The framework development was originally motivated to cover the needs of Rare Event Searches experiments (experiments looking for phenomena having extremely low occurrence probability, like dark matter or neutrino interactions or rare nuclear decays). The framework components naturally implement tools to address the challenges in these kinds of experiments. The integration of a detector physics response, the implementation of signal processing routines, or topological algorithms for physical event identification are some examples. Despite this specialization, the framework was conceived thinking in scalability. Other event-oriented applications could benefit from the data processing routines and/or metadata description implemented in REST, being the generic framework tools completely decoupled from dedicated libraries. REST-for-Physics is a consolidated piece of software already serving the needs of different physics experiments - using gaseous Time Projection Chambers (TPCs) as detection technology - for detector data analysis and characterization, as well as generic R&D. Even though REST has been exploited mainly with gaseous TPCs, the code could be easily applied or adapted to other detector technologies. We present in this work an overview of REST-for-Physics, providing a broad perspective to the infrastructure and organization of the project as a whole. The framework and its different components will be described in the text. [ABSTRACT FROM AUTHOR]

Abstract: The PVLAS experiment operates an ellipsometer based on a Fabry-Perot optical cavity that embraces a superconducting rotating dipole magnet and can measure the ellipticity induced by the magnetic field onto linearly polarized laser light. With a residual pressure less than 10−7 mbar the apparatus gives ellipticity signals at the level of 10−11 rad per passage through 1 m of 5 Tesla transverse magnetic field of 532 nm wavelength laser light. These signals can be interpreted as being generated largely by vacuum birefringence. If this interpretation is valid, a tool has become available to characterize physical properties of vacuum as if it were an ordinary transparent medium. The main source of the induced ellipticity could be the existence of ultralight bosons with mass of the order of 10−3 eV that would couple to two photons and would be created in the experiment by interactions of photons of the laser beam with virtual photons of the magnetic field. The apparatus is calibrated in amplitude and in phase by measuring Cotton-Mouton ellipticity in gases. The ellipticity induced in vacuum has phase opposite to that of the CME ellipticity induced with noble gases in the interaction region. If the ellipticity signals observed in vacuum are due to authentic quantum vacuum birefringence and not to the apparatus, and a microscopic interpretation of the effect in terms of existence of spin zero ultralight bosons is valid, the observed phase of the ellipticity implies a positive parity of the bosons. The ultralight bosons would then be scalars. [Copyright &y& Elsevier]

The PVLAS experiment operates an ellipsometer which embraces a superconducting dipole magnet and can measure ellipticity and rotation induced by the magnetic field onto linearly polarized laser light. The sensitivity of the instrument is about 10-7rad Hz-1/2. With a residual pressure less than 10-7 mbar the apparatus gives both ellipticity and rotation signals at the 10-7rad level with more than 8 sigma sob ratio in runs that last about 1000 sec. These signals can be interpreted as being generated largely by vacuum ellipticity and dichroism induced by the transverse magnetic field. If this interpretation is correct, a tool has become available to characterize physical properties of vacuum as if it were an ordinary transparent medium. A microscopic effect responsible for this induced dichroism could be the existence of ultralight spin zero bosons with mass of the order of , that would couple to two photons and would be created in the experiment by interactions of photons of the laser beam with virtual photons of the magnetic field. The inverse of the coupling constant to two photons would correspond to a mass M of the order of . [Copyright &y& Elsevier]
