D-instantons and matter hypermultiplet
Abstract We calculate the D-instanton corrections (with all D-instanton numbers) to the quantum moduli space metric of a single matter hypermultiplet with toric isometry, in the effective N=2 supergravity arising in type IIA superstrings...

Research of Large Field of View Scan Mode for Industrial CT
Abstract For industrial computed tomography systems, generation II scan mode has a large field of view but time-consuming and generation III has a small field of view but fast. In order to realize the rapid ICT test of large objects, a scan mode...

Physical Traces
Abstract Within the Geometry of Interaction (GoI) paradigm, we present a setting that enables qualitative differences between classical and quantum processes to be explored. The key construction is the physical interpretation/realization of the...

A predictive ansatz for neutrino mixing and leptogenesis
Abstract We propose a non-SO(10) modification of the Buchmüller–Wyler ansatz for neutrino mixing and leptogenesis, in which charged lepton, Dirac and Majorana neutrino mass matrices have fewer free parameters. Predictions of this new ansatz for...

Non-binding of flavor-singlet hadrons to nuclei
Abstract Strongly attractive color forces in the flavor singlet channel may lead to a stable H dibaryon. Here we show that an H or other compact, flavor singlet hadron is unlikely to bind to nuclei, so that bounds on exotic isotopes do not exclude...

Extending the region of triaxial superdeformation: candidate TSD bands in 174Hf
Abstract Three, possibly four, regularly spaced rotational bands with large dynamic moments of inertia have been identified in 174Hf. Their properties are consistent with known triaxial superdeformed bands of the Lu/Hf region. Calculations predict...

Dualities of the entropy bound
Abstract I study the hypothetical thermodynamic system which saturates the so-called Hubble entropy bound and show that it is invariant under the S- and T-dualities of string theory as well as the interchanges of the eleventh dimension of M-theory....

Diphoton production in gluon fusion at small transverse momentum
Abstract We discuss the production of photon pairs in gluon–gluon scattering in the context of the position-space resummation formalism at small transverse momentum. We derive the remaining unknown coefficients that arise at ...

Toroidal black holes and T-duality
Abstract We consider the toroidal black holes that arise as a generalization of the AdS 5×S 5 solution of type IIB supergravity. The symmetries of the horizon space allow T-duality transformations that can...

Experimental study of the e+e−→π0γ process in the energy region s=0.60–0.97 GeV
Abstract Results of the study of the e + e −→π 0 γ process with SND detector at VEPP-2M collider in the c.m.s. energy range ...

Soliton solutions for the N=2 supersymmetric KdV equation
Abstract The N=2 supersymmetric KdV equation of Inami and Kanno is bilinearized employing the Hirota method and the existence of N soliton solutions is demonstrated. The exact form of the solutions are explicitly obtained and an interesting symmetry ...

CP violating transverse lepton polarizaion in B→D(∗)ℓν̄ including tensor interactions
Abstract We give a model-independent analysis of CP violating lepton polarization in the exclusive semileptonic B decay of B→D(∗)ℓ ν ̄ including...

B-independence of RR charges
Abstract Generalization of the recent Taylor–Polchinski argument is presented, which helps to explain quantization of RR charges in IIA-like theories in the presence of cohomologically trivial H-fields.

Potential-shape effect on photoionization cross section of a donor in quantum dots
Abstract A donor impurity confined to a semiconductor quantum dot with the power-exponential potentials is considered as we study potential-shape effect. The power-exponential potential proposed is flexible enough to be applicable to both the...

Black holes in massive conformal gravity
Abstract We analyze the classical stability of Schwarzschild black hole in massive conformal gravity which was recently proposed for another massive gravity model. This model in the Jordan frame is conformally equivalent to the Einstein–Weyl gravity ...

Josephson Current in Superconductor-ferromagnet Structure with YBCO-LSMO
Abstract We have studied transport property of superconductor-ferromagnet hybridized structure in nanometer-scale processed by a focused ion beam technique. The structure was consisted of high-Tc superconductor YBa2Cu3O7-x and half metallic...

Strangeness production in light and intermediate size nucleus–nucleus collisions
Abstract Within the statistical model, the net strangeness conservation and incomplete total strangeness equilibration lead to the suppression of strange particle multiplicities. Furthermore, suppression effects appear to be stronger in small...

A Multiparameter Nuclear-fission Experiment: Can All be Obtained at Once?
Abstract A large variety of experimental works has been done since the discovery of nuclear fission, aimed at studying different aspects of the phenomenon. Yet our comprehension of the fission process is not complete. This is, among others, due to a ...

Trapping of spin-0 fields on tube-like topological defects
Abstract We have considered the localization of resonant bosonic states described by a scalar field Φ trapped in tube-like topological defects. The tubes are formed by radial symmetric defects in ( 2 ...
