Description

The 15th meeting in the conference series of Flavor Physics & CP Violation.

The FPCP conference series was founded in 2002 through the merger of the Heavy Flavor (HF) and B Physics and CP Violation (BPCP) conference series.

The aim of this conference is to review developments in flavor physics and CP violation, in both theory and experiment, exploiting the potential to study new physics at the LHC and future facilities. The topics include CP violation, rare decays, CKM elements with heavy quark decays, flavor phenomena in charged leptons and neutrinos, and also interplay between flavor and LHC high pT physics.

The program is composed of the invited oral talks. Participants are encouraged to submit abstracts for poster. Oral as well as poster presenters will be invited to publish their paper in the online proceedings.

        CP violation in charmed hadron decays into neutral kaons

        CP violation has not been observed in the charm sector. We find new measurable effect of CP asymmetries in the non-leptonic charmed hadron decaying into neutral kaons in the Cabibbo-favored and doubly Cabibbo-suppressed processes. Compared to the CP asymmetries in the singly Cabibbo-suppressed processes, the advantages of this new effect include avoiding ambiguities in theory without penguin contributions, and having larger branching fractions for measurements in experiment. The values of such CP asymmetries are at the order of 10^{-3} and hence are accessible by the LHCb and Belle II experiments in the near future. Besides, the measurement and determination of time-dependent CP asymmetries at t=0 is a smoking gun of direct CP violation in charm decays and signal of new physics.

        Search for new physics via baryon EDM at LHC

        Permanent electric dipole moments (EDMs) of fundamental particles provide powerful probes for physics beyond the Standard Model. We propose to search for the EDM of strange and charm baryons at LHC, extending the ongoing experimental program on the neutron, muon, atoms, molecules and light nuclei. The EDM of strange Λ baryons, selected from weak decays of charm baryons produced in pp collisions at LHC, can be determined by studying the spin precession in the magnetic field of the detector tracking system. A test of CPT symmetry can be performed by measuring the magnetic dipole moment of Λ and anti-Λ baryons. For short-lived Λc+ and Ξc+ baryons, to be produced in a fixed-target experiment using the 7 TeV LHC beam and channeled in a bent crystal, the spin precession is induced by the intense electromagnetic field between crystal atomic planes. A possible realisation of this programme would be at the LHCb experiment. In this scenario the experimental layout based on the LHCb detector and the expected sensitivities in the coming years are discussed, along with perspectives for the future.

        Implication of ALEPH 30 GeV dimuon excess at the LHC

        Recent reanalysis of ALEPH data on $Z\rightarrow b\bar{b} + X$ seems to indicate an existence
        of the dimuon excess around 30 GeV with a branching fraction for
        $Z\rightarrow b\bar{b} \mu^+ \mu^-$ around $1.1 \times10^{-5}$.
        We discuss three different types of simplified models for this possible excess.
        In the first class of models, we assume a new resonance couples to both $b\bar{b}$ and $\mu^+ \mu^-$.
        In the second model, we assume that the 30 GeV excess is a new gauge boson $Z'$ that couples
        to the SM $b$ and a new vectorlike singlet $B$ quark heavier than $Z$ and not to $b\bar{b}$.
        In the third model, we consider $Z\rightarrow Z' \phi$ followed by $Z' \rightarrow \mu^+ \mu^-$ and
        $\phi \rightarrow b\bar{b}$ assuming that the Higgs field for $Z'$ mass is also charged under the SM
        $U(1)_Y$ gauge symmetry.
        We consider constraints on the models and investigate implication of the three models at the LHC.

        DsixTools: The Standard Model Effective Field Theory Toolkit

        I will present DsixTools, a Mathematica package for the handling of the dimension-six Standard Model Effective Field Theory. Among other features, DsixTools allows the user to perform the full one-loop Renormalization Group Evolution of the Wilson coefficients in the Warsaw basis. This is achieved thanks to the SMEFTrunner module, which implements the full one-loop anomalous dimension matrix previously derived in the literature. In addition, DsixTools also contains modules devoted to the matching to the ΔB=ΔS=1,2 and ΔB=ΔC=1 operators of the Weak Effective Theory at the electroweak scale and their QCD and QED Renormalization Group Evolution below the electroweak scale.

        Scalar dark matter with top-quark portal

        A scalar dark matter model interacting with the standard model sector via top-quark portal as well as Higgs portal is presented. In the model a scalar dark matter $S$ and a vector-like fermion $T$ are new physics particles and assumed to have odd parity under a $Z_2$ symmetry, while all the standard model fields have even parity. The impacts of new top-quark portal interaction, $y_{ST} S \bar{T} t_R +h.c$, on dark matter phenomenology and collider searches will be emphasized.

        B physics Beyond the Standard Model at One Loop: Complete Renormalization Group Evolution below the Electroweak Scale

        General analyses of $B$-physics processes beyond the Standard Model require accounting for operator mixing in the renormalization-group evolution from the matching scale down to the typical scale of $B$-meson mixing and decay. For
        this purpose the anomalous dimensions of the full set of local dimension-six operators beyond the Standard Model are needed. We present here for the first time a complete set of non-redundant dimension-six operators relevant for $B$ physics, together with the complete one-loop anomalous dimensions in QCD and QED. These results are an important step towards the automation of general New Physics analyses.

        iangmen Underground Neutrino Observatory (JUNO) facility and detector design

        iangmen Underground Neutrino Observatory (JUNO), a next generation underground reactor antineutrino experiment, is proposed to determine the neutrino mass hierarchy using a massive liquid scintillator detector underground. The experimental hall, spanning more than 50 meters, is under a granite mountain of over 700 m overburden. The central antineutrino detector, built with 35.4-meter diameter acrylic sphere, contains 20 kilotons of liquid scintillator and ~18,000 20 inch PMTs (and ~20,000 3 inch PMTs). The antineutrino detector is placed in a water pool shielding system which also functions as an active water Cherenkov veto detector. On the top of water pool is a Top Tracker system which further improves the muon track reconstruction. This poster presents the JUNO facility and detector design.

        Lepton asymettry in S_3 extended Standard Model

        Standard Model (SM) of electroweak interaction seems to be complete and consistent with almost all the data obtained so far, nevertheless, some deviations in the B sector are observed apart from the neutrino oscillation. It is believed that the SM is not a complete theory as we cannot explain the matter-anti matter asymmetry in our Universe in addition to the fact that the visible Universe contains just ~5% of the total energy budget. We consider Leptogenesis in a minimal $S_3$ extended standard model with a Higgs doublet and 3 right handed singlet Majorana neutrinos. We study the neutrino phenomenology from the flavor structure of the $S_3$ invariant mass matrix and obtained the allowed parameter space for Dirac and Majorana phases. We have chosen the out of equilibrium decays of the right handed Majorana neutrinos to be in the temperature range of $10^9$ to $10^{12}$ GeV, where one flavor approximation is ruled out as the tau lepton comes to equilibrium. Hence we can distinguish between the $\tau$ and other leptons flavor. Thereafter, we generate the lepton asymmetry by adding flavor effects coming individually from both $\tau$ and other leptons sector. This two flavor approximation can generate an appreciable lepton asymmetry which can convert to the baryon asymmetry through sphaleron process which is in compatible with the experimental observation.

        JUNO supernovae neutrino potential

        Determination of neutrino mass hierarchy is the main purpose of Jiangmen Underground Neutrino Observatory (JUNO). JUNO is designed to determine neutrino mass hierarchy by a detailed examination of the spectrum of electron antineutrinos from nuclear reactors. The analysis of neutrino energy spectra emitted by a supernova represents another possible way to determine neutrino mass hierarchy because neutrino flavor conversions occurring inside the supernova are sensitive to neutrino mass hierarchy. The aim of this study is to explore the possibility of JUNO to distinguish between neutrino flavors coming in a supernova burst and measure their energy spectra. A set of observables and criteria is proposed that enable on the basis of measured neutrino energy spectra to distinguish between normal and inverted neutrino mass hierarchy and to prove or disprove some supernova theoretical models.

        Alignment and physics performance of the Belle II vertex detector

        The Belle II experiment at the SuperKEKB accelerator will start to take physics data in 2018. One of the major upgrades of the Belle II detector introduces a DEPFET pixel sensors in the two innermost layers of its silicon vertex detector, followed by four layers of silicon strip sensors. Excellent performance of the vertex reconstruction is a crucial ingredient in CP violation measurements and will require reliable and fast alignment procedure and continuous monitoring of the detector performance. To address the possible systematic errors of the procedure, a dedicated study has been performed to identify and evaluate influence of possible random and systematic deformations of the vertex detector on physics observables.
