We show that this scenario can account for the detected X‐ray emission. We demonstrate that GLAST will conclusively test the dark matter annihilation hypothesis. Depending on the particle dark matter model, GLAST might even detect the monochromatic line produced by dark matter pair annihilation into two photons.","PeriodicalId":54708,"journal":{"name":"Nuovo Cimento Della Societa Italiana Di Fisica B-Basic Topics in Physics","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2009-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1063/1.3052024","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"58566463","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A new generation of quasi-monochromatic, high-flux X-ray sources is currently under development, based on Thomson scattering of photons produced by a laser on a highly focused electron beam. In this paper we investigate the effect of different spectral distributions on the image contrast on 2 cm, 4 cm, 6 cm, 8 cm breast mammographic phantoms containing details of different composition (tumor mass and calcification details) and thickness. In the simulations we assume a homogeneous breast composition and three compositions (25%; 50% and 75% glandular) are investigated. We simulate monochromatic, quasi-monochromatic and polychromatic X-ray sources in order to define the optimal energies that maximize the image quality parameter. In particular we compare the simulations of the Gaussian quasi-monochromatic spectra. having different energy standard deviations (1, 2, 3, 4, 5 keV) with traditional X-ray tubes spectra. Results show that Gaussian spectra having an energy spread of about 1 keV standard deviation call improve the image quality of about 30% with respect to traditional X-ray tube ones.","PeriodicalId":54708,"journal":{"name":"Nuovo Cimento Della Societa Italiana Di Fisica B-Basic Topics in Physics","volume":"124 1","pages":"205-222"},"PeriodicalIF":0.0,"publicationDate":"2009-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66579040","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We find that the phase of the Bs mixing amplitude deviates about 2.5σ from the Standard Model prediction. While no single Tevatron experiment has a significant evidence yet, all the constraints show a remarkable agreement with the combined result. This is an interesting hint of physics beyond the Standard Model. In particular, this result disfavours New Physics models with Minimal Flavour Violation with the same significance.","PeriodicalId":54708,"journal":{"name":"Nuovo Cimento Della Societa Italiana Di Fisica B-Basic Topics in Physics","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2008-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1063/1.3051953","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"58566439","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
