Updated NLL Results for B -> (Xs,Xd) gamma in and beyond the SM
We present general model-independent formulae for the branching ratios and
the direct tagged CP asymmetries for the inclusive B -> Xd gamma and B -> Xs
gamma modes. We also update the corresponding SM predictions.Comment: 3 pages, Contribution to the International Europhysics Conference on

General Flavor Blind MSSM and CP Violation
We study the implications on flavor changing neutral current and CP violating
processes in the context of supersymmetric theories without a new flavor
structure (flavor blind supersymmetry). The low energy parameters are
determined by the running of the soft breaking terms from the grand unified
scale with SUSY phases consistent with the EDM constraints. We find that the CP
asymmetry in b --> s gamma can reach large values potentially measurable at B
factories, especially in the low BR(b --> s gamma) region. We perform a fit of
the unitarity triangle including all the relevant observables. In this case, no
sizeable deviations from the SM expectations are found. Finally we analyze the
SUSY contributions to the anomalous magnetic moment of the muon pointing out
its impact on the b --> s gamma CP asymmetry and on the SUSY spectrum including
chargino and stop masses.Comment: 40 pages, 8 figures, typos corrected, references adde
General Flavour Blind MSSM and CP Violation
We study FCNC and CP violating processes in the MSSM without a new flavour
structure (flavour blind MSSM). The low energy parameters are determined by the
running of the soft breaking terms from the GUT scale with SUSY phases
consistent with the EDM constraints. We find that the CP asymmetry in b -> s
gamma can reach large values potentially measurable at B factories, especially
in the low BR(b -> s gamma) region. We analyze the SUSY contributions to the
anomalous magnetic moment of the muon pointing out its impact on the b -> s
gamma CP asymmetry and on the SUSY spectrum.Comment: LaTex, 5 pages, 2 figures, Contribution to the International

Cardiorespiratory DB: Collection of cardiorespiratory data acquired during normal breathing, deep breathing and breath holding
The database is constituted by 50 datasets containing cardiorespiratory signals acquired from 50 healthy volunteer subjects (one dataset for each subject; 23 males and 27 females; age: 23±5 years) while performing normal breathing, deep breathing, and breath holding, and two spreadsheet files, namely the âSubjectsInfo.xlsxâ and âDBInfo.xlsxâ containing the metadata of subjects (including demographic data) and of acquired signals, respectively. Cardiorespiratory signals consisted in simultaneously recorded 12-lead electrocardiograms acquired by the clinical M12 Global InstrumentationR digital Holter ECG recorder, and single-lead electrocardiograms and respiration signals acquired by the wearable chest strap BioHarness 3.0 by Zephyr. The database may be useful to: (1) validate the use of wearable sensors in the acquisition of cardiorespiratory data during different respiration kinds, including apnea; (2) investigate the physiological association between cardiovascular and respiratory systems; (3) validate algorithms able to indirectly extract the respiration signal from the electrocardiogram; (4) study the fatigue level induced by a series of controlled respiration patterns; and (5) investigate the effect of COVID-19 infection on the cardiorespiratory system
Recent developments in radiative B decays
We report on recent theoretical progress in radiative B decays. We focus on a
calculation of logarithmically enhanced QED corrections to the branching ratio
and forward-backward asymmetry in the inclusive rare decay anti-B --> X(s) l+
l-, and present the results of a detailed phenomenological analysis. We also
report on the calculation of NNLO QCD corrections to the inclusive decay anti-B
--> X(s) gamma. As far as exclusive modes are concerned we consider
transversity amplitudes and the impact of right-handed currents in the
exclusive anti-B --> K^* l+ l- decay. Finally, we state results for exclusive B
--> V gamma decays, notably the time-dependent CP-asymmetry in the exclusive B
--> K^* gamma decay and its potential to serve as a so-called ``null test'' of
the Standard Model, and the extraction of CKM and unitarity triangle parameters
from B --> (rho,omega) gamma and B --> K^* gamma decays.Comment: 5 pages, 2 figures. Accepted for publication in the proceedings of

Patient Active Approaches in Osteopathic Practice: A Scoping Review
Background: In the field of manual therapies there is a growing interest in moving from passive hands-on approaches to patient active approaches. In the osteopathic field there are both active and passive methods described as integrated in the process of care. However, this prospective linkage has not been formally explored and is not well shared in the community of practice. The present review aims to appraise the relevant literature on the functioning and principles of Patient active osteopathic approaches (PAOAs) and explore a prospective model for selecting the different types of PAOA, highlighting their integration into patient management strategies. Methods: A scoping review was conducted to analyze the relevant literature on the functioning and the different principles of PAOA and to obtain a comprehensive perspective on the phenomenon. Results: The eligible articles provide insights into the mechanisms of functioning and principles of application of active approaches to be integrated with hands-on approaches. These results provide new insights into the relevance of PAOA to clinical practice. Conclusions: The proposal, emerging from the review, may promote discussions in the community of practice and provide a road map for research towards achieving an evidence-based structure for PAOA
Complete Anatomy of B -> K*ll and its angular distribution
We present a complete and optimal set of observables for the exclusive 4-body
B meson decay B -> K*(->K pi) l+l- in the low dilepton mass region, that
contains a maximal number of clean observables. This basis of observables is
built in a systematic way. We show that all the previously defined observables
and any observable that one can construct, can be expressed as a function of
this basis. This set of observables contains all the information that can be
extracted from the angular distribution in the cleanest possible way. We
provide explicit expressions for the full and the uniangular distributions in
terms of this basis. The conclusions presented here can be easily extended to
the large-q^2 region. We study the sensitivity of the observables to
right-handed currents and scalars. Finally, we present for the first time all
the symmetries of the full distribution including massive terms and scalar
contributions.Comment: 37 pages, 12 Figures. Corrected typo in Eqs. (29) and (44). Results

CP Asymmetry of in Low Invariant Mass Region
I analyzed the CP asymmetry of based on model-independent
analysis which includes twelve independent four Fermi operators. The CP
asymmetry is suppressed in the Standard Model, however, if some new physics
make it much larger, the present or the next generation B factories may catch
the CP violation in this decay mode. In this paper, we studied the correlation
of the asymmetry and the branching ratio, and then we will find only a type of
interactions can be enlarge the asymmetry. Therefore, in comparison with
experiments, we have possibility that we can constrain models beyond the
standard model.Comment: 12 pages, 5 figures, LaTeX, Accepted for Physical Review
Rare Decays as a Probe for New Physics
We discuss the indirect search for new degrees of freedom beyond the standard
model, within flavour physics. In particular, we analyse the minimal flavour
violation hypothesis and its phenomenological implications, especially the
large-tan beta scenario in supersymmetric models, and also compare it with the
constrained minimal flavour violation scenario. Moreover, we briefly discuss
some recent progress in inclusive b to s transitions and present a status
report of the so-called K-pi puzzle.Comment: 8 pages, 6 figures, based on an invited review talk given at Beauty

Exploring New Physics in the C7-C7' plane
The Wilson coefficient C7 governing the radiative electromagnetic decays of B
meson has been calculated to a very high accuracy in the Standard Model, but
experimental bounds on either the magnitude or the sign of C7 are often
model-dependent. In the present paper, we attempt at constraining both the
magnitude and sign of C7 using a systematic approach. We consider already
measured observables like the branching ratios of B \rightarrow Xs mu+ mu- and
B \rightarrow Xs gamma, the isospin and CP asymmetries in B \rightarrow K*
gamma, as well as AFB and FL in B \rightarrow K*l+l-. We also discuss the
transverse observable AT2 which, once measured, may help to disentangle some of
the scenarios considered. We explore the constraints on C7, C9, C10 as well as
their chirality-flipped counterparts. Within our framework, we find that we
need to extend the constraints up to 1.6 sigma to allow for the "flipped-sign
solution" of C7. The SM solution for C7 exhibits a very mild tension if New
Physics is allowed in dipole operators only. We provide semi-numerical
expressions for all these observables as functions of the relevant Wilson
coefficients at the low scale.Comment: 54 pages, 16 figures, 15 tables. Normalization factor introduced for
the integrated AFB and FL in Sec.2.5 (Eq.2.35-2.38). Conclusions unchanged.
