We present the physics program of Belle II experiment, located on intensity frontier SuperKEKB $e^+e^-$ collider. collected its first collisions in 2018, and is expected to operate for next decade. It anticipated collect 50/ab collision data over lifetime. This book outcome a joint effort collaborators theorists through theory interface platform (B2TiP), an that commenced 2014. The aim B2TiP was elucidate potential impacts program, which includes wide scope topics: B physics, charm, tau,...
In the original version of this manuscript, an error was introduced on pp352. '2.7nb:1.6nb' has been corrected to '2.4nb:1.3nb' in current online and printed version. doi:10.1093/ptep/ptz106.
It has been realized for a long time that knowing the eta and eta^prime wave functions in terms of quark gluon components probes our understanding non-perturbative QCD dynamics. Great effort given to this challenge -- yet no clear picture emerged even with most recent KLOE data. We point out which measurements would be helpful arriving at more definite conclusion. A better knowledge these will significantly help disentangle weight different decay subprocesses semi-leptonic decays D+, Ds^+ B+...
The Q $\&$ U Bolometric Interferometer for Cosmology (QUBIC) is a novel kind of polarimeter optimized the measurement B-mode polarization Cosmic Microwave Background (CMB), which one major challenges observational cosmology. signal expected to be order few tens nK, prone instrumental systematic effects and polluted by various astrophysical foregrounds can only controlled through multichroic observations. QUBIC designed address these issues with approach that combines advantages...
We discuss as accurately possible the cross section of quasi-elastic scattering electron (anti-)neutrinos on nucleons, also known inverse beta decay in case antineutrinos. focus moderate energy range from a few MeV up to hundreds MeV, which includes neutrinos reactors and supernovae. assess uncertainty section, is relevant experimental advances increasingly large statistical samples. estimate effects second-class currents, showing that they are small negligible for current applications.
Observations of protoplanetary disks within multiple systems in nearby star-forming regions (SFRs) have shown that the presence a neighboring object influences evolution dust disks. However, size available sample and separation range covered are insufficient to fully understand binary systems. The goal this work, based on Survey Orion Disks with ALMA (SODA), is comprehensively characterize impact stellar multiplicity Class II L1641 L1647 A (∼ 1-3 Myr). We characterized protostellar using...
Supernova neutrinos are of considerable importance for ongoing research in astrophysics, nuclear and particle physics. Existing simulations this complex event increasingly sophisticated, but the accuracy with which they describe emission is unknown. The only observed so far neutrino telescopes, SN1987A, still plays a crucial role deserves to be studied meticulously. With mind, we have undertaken refined analysis observations, taking into account knowledge gained over past decades. In work,...
By adopting a state-of-the-art parameterized model of electron antineutrino emission, we have made some steps forward in the analysis thermodynamical properties and temporal structure neutrino emission from core collapse SN1987A. Our analysis, unlike similar previous ones, takes into account times, energies angles arrival detected events reliable framework which includes finite ramp initial stage emission. The existence accretion phase is confirmed with confidence level about 99%, neutrons...
We consider the see-saw mechanism within a nonsupersymmetric SO(10) model. By assuming quark-lepton symmetry, and after imposing suitable conditions that ensure right-handed neutrino masses are at most mildly hierarchical (compact spectrum) we obtain surprisingly predictive scenario. The absolute mass scale, Dirac two Majorana phases of mixing matrix remain determined in terms set already measured low energy observables, modulo discrete ambiguity signs angles phase. spectrum is also...
Despite being remarkably predictive, the Standard Model leaves unanswered several important issues, which motivate an ongoing search for its extensions. One fashionable possibility are so-called 331 models, where electroweak gauge group is extended to <a:math xmlns:a="http://www.w3.org/1998/Math/MathML" display="inline"><a:msub><a:mi>SU</a:mi><a:mi>L</a:mi></a:msub><a:mo stretchy="false">(</a:mo><a:mn>3</a:mn><a:mo stretchy="false">)</a:mo><a:mo>×</a:mo><a:mi...
We present a complete calculation of the leading-order QCD corrections to quark level decay amplitude for $b\ensuremath{\rightarrow}s\ensuremath{\gamma}\ensuremath{\gamma}$ and study their relevance both inclusive branching ratio $B(B\ensuremath{\rightarrow}{X}_{s}\ensuremath{\gamma}\ensuremath{\gamma})$ exclusive channel ${B}_{s}\ensuremath{\rightarrow}\ensuremath{\gamma}\ensuremath{\gamma}$. In addition uncertainties in short distance calculation, due choice renormalization scale, an...
We discuss non-perturbative corrections to the neutrino sector, in context of a D-brane Pati-Salam-like model, that can be obtained as simple alternative $SO(10)$ GUT's theories with open and unoriented strings. In such models, exotic stringy instantons correct right-handed mass matrix calculable way, thus affecting hierarchies modifying see-saw mechanism what we name see-saw. For wide range parameters, compact spectrum masses occur gives rise predictive scenario for low energy observables....
Bolometric interferometry is a novel technique that has the ability to perform spectral imaging. A bolometric interferometer observes sky in wide frequency band and can reconstruct maps several sub-bands within physical post-processing of data. This provides powerful method discriminate between cosmic microwave background (CMB) astrophysical foregrounds. In this paper, methodology illustrated with examples based on Q \& U Interferometer for Cosmology (QUBIC) which ground-based instrument...
