Summary: The study presents a global analysis of the low-energy phenomenology of the minimal left-right symmetric model (mLRSM) with parity symmetry, determining a lower bound on the mass of the right-handed W-R boson. In models where a Peccei-Quinn mechanism is present, a mass of M-WR greater than or similar to 5.5TeV at 95% C.L. is obtained, which can be improved with next-generation EDM experiments. However, in P-symmetric mLRSM without the Peccei-Quinn mechanism, a more stringent constraint of M-WR greater than or similar to 17TeV at 95% C.L. is found.

Summary: The left-right symmetric model is a well-motivated framework for restoring parity and implementing seesaw mechanisms for tiny neutrino masses. This paper examines the phase transition and gravitational waves in the minimal version of LRSM, identifying parameter regions with strong first-order phase transition and detectable GWs. It is found that in a substantial region of the parameter space, GWs can be generated in the phase transition and favor a relatively light SU(2)(R)-breaking scalar H30, which complements direct searches at high-energy colliders.

Summary: This study focuses on the impact of the Higgs scalar sector in the conventional left-right gauge model on fermion masses, and how all standard-model fermions may acquire realistic masses radiatively with the help of a dark sector with U(1)(D) gauge symmetry. The particle content of the model also implies the automatic conservation of baryon number B and lepton number L, while predicting observable anomalous Higgs couplings.

Summary: In this study, the CP-violating scalar axion coupling to nucleons was computed using baryon chiral perturbation theory and applied to the case of left-right symmetry. The results suggest that the predicted axion nucleon coupling is testable within the scope of present axion-mediated force experiments for M-WR up to 1000 TeV when considering correlated constraints with other CP-violating observables.

Summary: In this study, we analyzed the ability of convolutional neural networks (CNNs) to discriminate between right and left fundus images. Through the use of fundus photograph datasets and augmentation techniques, we found that CNNs accurately identified right and left fundus images, with the depth and complexity of the CNN affecting accuracy. Additionally, we discovered that the flipping method used for data augmentation in fundus photographs may introduce undesired bias.

Summary: The symmetry breaking of solitons in the nonlinear Schrodinger equation with cubic-quintic competing nonlinearity and parity-time symmetric potential is studied. It is found that symmetric fundamental solitons and symmetric tripole solitons tend to be stable, while asymmetric solitons are unstable in both high and low power regions. Increasing saturable nonlinearity widens the stability region of fundamental symmetric solitons and symmetric tripole solitons.

Summary: In this work, we studied neutrinoless double beta decay and charged lepton flavor violation in a generic left-right symmetric model. We used a discrete flavor symmetry to realize the model and considered different contributions to the decay process. We also analyzed the relationship between charged lepton flavor violation and neutrino mass.

Summary: A model of symmetry breaking charge separation in symmetric excited dyads and dimers is presented. The model includes at least four basis electronic states with electronic couplings between them. The study shows that the degree of charge separation can be controlled by adjusting the model parameters, and the predictions of the model agree with experimental data.

Summary: We investigate an alternative left-right model (ALRM) that is not symmetric under the exchange of fermion content, but can be embedded in E-6 and has a low energy Higgs structure similar to the traditional left-right symmetric models (LRSM). By analyzing the scalar potential and vacuum structure, we ensure the stability of the scalar potential and derive constraints on various coupling parameters through numerical study.

Summary: We study a variant of the left-right symmetric model with Dirac type neutrinos. The model incorporates heavy vector-like fermions and different scalar multiplets to generate non zero neutrino mass through loop mediated processes. The parameters involved in the neutrino mass generation mechanism satisfy the neutrino oscillation data for both normal and inverted hierarchy. The lightest charged Higgs is crucial in the neutrino mass generation mechanism and can have a mass of O[GeV]. We also discuss constraints relevant to the charged Higgs phenomenology and the discovery prospects of the charged Higgs at different colliders.

Summary: The body axis of vertebrate embryos is segmented into bilaterally symmetric pairs of somites. In zebrafish embryos, the initial lengths and positions of somites are imprecise, leading to left-right asymmetry. However, these asymmetries are adjusted within an hour after somite formation through changes in somite shape, increasing morphological symmetry. This adjustment mechanism is facilitated by somite surface tension and is not affected by perturbations to the segmentation clock.

Summary: The development of visceral left-right asymmetry in bilateria relies on initial symmetry breaking and subsequent molecular patterning. The expression of the transcription factor pitx2 on the left side is facilitated by the asymmetric expression of the nodal morphogen in the left lateral plate mesoderm. The mechanisms leading to the asymmetric nodal domain differ depending on the mode of symmetry breaking.

Summary: This study systematically investigates new physics scenarios that can modify the interactions between neutrinos and matter, with a focus on the importance of tau neutrino telescopes in probing physics associated with the second and third generations. By analyzing experimental configurations and numerically solving propagation equations, the study obtains the sensitivities of upcoming tau neutrino telescopes to charged Higgs and leptoquark models. The combination of different telescopes is complementary in exploring new physics.

Summary: The measurements from the coherent elastic neutrino-nucleus scattering (CE nu NS) experiments have opened up possibilities to study neutrino physics beyond the standard model. This paper presents constraints on non-standard interactions (NSIs) and mediators derived from CONUS germanium data. The study found that the CONUS experiment has set the world's best limits on tensor NSIs and has the potential to probe coupling constants for scalar and vector mediators.

Summary: Anomalies in past neutrino measurements have led to the discovery of non-zero neutrino mass and oscillation between different flavors. The STEREO experiment aimed to investigate the existence of a supplementary, sterile neutrino state that does not interact via weak interaction. The analysis of data from the STEREO experiment confirms observed anomalies while rejecting the hypothesis of a light sterile neutrino.

Summary: This study analyzes the potential of the proposed mu(+)mu(+) and mu(+)e(-) collider mu TRISTAN in complementing the searches for charged-lepton flavour-violation (CLFV) conducted by Belle II. It finds that mu TRISTAN can directly produce and study new resonances that could mediate CLFV within a certain mass range, and it can also provide competitive bounds in cases where the new resonance is beyond direct reach. Three Z(3) lepton triality models are used as examples to illustrate these points, and the sensitivity of mu TRISTAN for each process is quantified.

Summary: In this study, we investigate whether the high-precision measurements of the cross section of the Higgsstrahlung process e(+) e(-) -> Zh at a future electron-positron collider can be used to indirectly probe the fermionic See-saw models. We consider two different centre-of-mass energies and compare the collider reaches to various constraints. We find that while the Type-I Seesaw model is strictly constrained, the Type-III Seesaw model allows for effects of up to O(10%) in the Higgsstrahlung cross section.

Summary: Motivated by flavor symmetry models, we propose theories with lepton flavor triality in the low-energy limit, which predict the presence of flavor-violating decays tau +/- -> mu +/- mu +/- e and tau +/- -> e +/- e +/- mu as the main phenomenological signatures beyond the standard model. These decays are expected to be investigated with improved sensitivity by the Belle II experiment at the SuperKEKB collider. We analyze the phenomenology of these theories, which involve doubly charged scalars mediating the above-mentioned decay processes.

Summary: We propose an extension of the Standard Model by introducing a scalar leptoquark to explain anomalies in charged-current semileptonic B meson decays and the muon anomalous magnetic moment. This extension also accounts for charged fermion masses and quark mixing. By using a discrete flavor symmetry, the couplings between the leptoquark and the first generation of quarks and/or electrons are suppressed, thus avoiding experimental bounds. Our study demonstrates that it is feasible to simultaneously explain the data on lepton flavor universality ratios and the muon anomalous magnetic moment, while satisfying other flavor observables.

Summary: The rare decays of B mesons provide strong constraints on the mixing of a light scalar with the Higgs boson. The constraints depend on the branching ratios to muons and may be weakened by additional decay channels. Belle II will investigate this scenario. The complementarity of scalar decays to muons and invisible decays is illustrated using results from LHCb and BaBar, and two simple models are provided.

Summary: Within the effective-field-theory framework, this study presents a model-independent analysis of the potential of discovering new physics through lepton flavor violation in heavy quarkonium decays. It computes the constraints from LFV muon and tau decays on new-physics operators and provides a comprehensive list of indirect upper limits on LFV processes. The results show that the constraints are stringent and make the detection of quarkonium decays into e mu difficult, while improvements in sensitivities are required for the detection of decays into lt. Additionally, searches for LFV Z decays at future e(+) e(+) colliders are found to be complementary probes of 2q2l operators with third generation quarks.
