Timelike-helicity $B→ππ$ form factor from light-cone sum rules with dipion distribution amplitudes

2017-09-26T10:00:00+00:00

Author(s): Shan Cheng, Alexander Khodjamirian, and Javier Virto

We complete the set of QCD light-cone sum rules for $B→ππ$ transition form factors, deriving a new sum rule for the timelike-helicity form factor ${F}_{t}$ in terms of dipion distribution amplitudes. This sum rule, in the leading twist-two approximation, is directly related to the pion vector form f...

Author(s): Zhi-Yong Zhou and Zhiguang Xiao

We developed a Friedrichs-model-like scheme in studying the hadron resonance phenomenology and present that the hadron resonances might be regarded as the Gamow states produced by a Hamiltonian in which the bare discrete state is described by the result of the usual quark potential model and the int...

Scalar and vector form factors of $D→π(K)ℓν$ decays with ${N}_{f}=2+1+1$ twisted fermions

Author(s): V. Lubicz, L. Riggio, G. Salerno, S. Simula, and C. Tarantino (for the ETM Collaboration)

We present a lattice determination of the vector and scalar form factors of the $D→πℓν$ and $D→Kℓν$ semileptonic decays, which are relevant for the extraction of the CKM matrix elements $|{V}_{cd}|$ and $|{V}_{cs}|$ from experimental data.

Testing the threshold expansion for three-particle energies at fourth order in ${ϕ}^{4}$ theory

Author(s): Stephen R. Sharpe

A relativistic formalism for relating the energies of the states of three scalar particles in finite volume to infinite volume scattering amplitudes has recently been developed. This formalism has been used to predict the energy of the state closest to threshold in an expansion in powers of $1/L$, w...

$B$ decay anomalies from non-Abelian local horizontal symmetry

Author(s): James M. Cline and Jorge Martin Camalich

Recent anomalies in $B→{K}^{(*)}ℓℓ$ meson decays are consistent with exchange of a heavy ${Z}^{′}$ vector boson. Here we try to connect such new physics to understanding the origin of flavor, by gauging generation number. Phenomenological and theoretical considerations suggest that the smallest viab...

Author(s): Diogo Buarque Franzosi and Piero Ferrarese

The strong nature of composite Higgs models manifests at high energies through the growing behavior of the scattering amplitudes of longitudinally polarized weak bosons that leads to the formation of composite resonances as well as nonresonant strong effects. In this work the unitarity of these scat...

Relativistic ultracompact objects without an event horizon may be able to form in nature and merge as binary systems, mimicking the coalescence of ordinary black holes. The postmerger phase of such processes presents characteristic signatures, which appear as repeated pulses within the emitted gravi...

Black hole squeezers

We show that the gravitational quasinormal modes (QNMs) of a Schwarzschild black hole play the role of a multimode squeezer that can generate particles. For a minimally coupled scalar field, the QNMs “squeeze” the initial state of the scalar field (even for the vacuum) and produce scalar particles. ...

Author(s): Francesco Maione, Roberto De Pietri, Alessandra Feo, and Frank Löffler

In this work we analyze the gravitational wave signal from hypermassive neutron stars formed after the merger of binary neutron star systems, focusing on its spectral features. The gravitational wave signals are extracted from numerical relativity simulations of models already considered by De Pietr...

Scalar perturbations of nonsingular nonrotating black holes in conformal gravity

2017-09-19T10:00:00+00:00

Author(s): Bobir Toshmatov, Cosimo Bambi, Bobomurat Ahmedov, Zdeněk Stuchlík, and Jan Schee

We study scalar and electromagnetic perturbations of a family of nonsingular nonrotating black hole spacetimes that are solutions in a large class of conformally invariant theories of gravity. The effective potential for scalar perturbations depends on the exact form of the scaling factor. Electroma...
