On the aether-like Lorentz-breaking action for the electromagnetic field
We study the generation of aether-like Lorentz-breaking actions in three, four and five dimensions via an appropriate Lorentz-breaking coupling of electromagnetic and spinor fields. Special attention is given to the four-dimensional case where we discuss the issue of ambiguities.

title: Effective potential for a SUSY Lee–Wick model: The Wess–Zumino case
abstract: Using a superfield generalization of the tadpole method, we study the one-loop effective potential for a Wess–Zumino model modified by a higher derivative term, inspired by the Lee–Wick model. The one-loop Kahlerian potential is also obtained by other methods and compared with the effective potential.

title: Free energy of Lorentz-violating QED at high temperature
abstract: In this paper we study the one- and two-loop contribution to the free energy in QED with Lorentz symmetry breaking introduced via constant CPT-even Lorentz-breaking parameters at the high temperature limit. We find the impact of the Lorentz-violating term for the free energy and carry out a numerical estimation for the Lorentz-breaking parameter.

title: Horava-Lifshitz-like extensions of supersymmetric theories
abstract: Within the superfield approach, we formulate two different extensions of the Wess-Zumino model and super-QED with Horava-Lifshitz-like additive terms, discuss their quantum properties and calculate lower contributions to the effective action. In the case of the gauge theory, the one-loop effective potential turns out to be gauge independent.

title: Equivalence between supersymmetric self-dual and Maxwell–Chern–Simons models coupled to a matter spinor superfield
abstract: We study the duality of the supersymmetric self-dual and Maxwell–Chern–Simons theories coupled to a fermionic matter superfield, using a master action. This approach evades the difficulties inherent to the quartic couplings that appear when matter is represented by a scalar superfield. The price is that the spinorial matter superfield represents a unusual supersymmetric multiplet, whose main physical properties we also discuss.

title: Lorentz violation and the proper-time method
abstract: In this Letter, we apply the proper-time method to generate the Lorentz-violating Chern–Simons terms in the four-dimensional Yang–Mills and non-linearized gravity theories. It is shown that the coefficient of the induced Chern–Simons term is finite but regularization dependent.

title: X(3872) in effective field theory
abstract: We consider the implications from the possibility that the recently observed state X(3872) is a meson‐antimeson molecule. We write an effective Lagrangian consistent with the heavy‐quark and chiral symmetries needed to describe X(3872) and study its properties.

title: Searching for super-WIMPs in leptonic heavy meson decays
abstract: We study constraints on the models of bosonic super-weakly interacting particle (super-WIMP) dark matter (DM) with DM masses m X ∼ O ( 1 – 100 ) keV from leptonic decays M → l ν ¯ l + X , where M = B ± , D ± , D s ± is a heavy meson state. We focus on two cases where X denotes either a light pseudoscalar (axion-like), or a light vector state that couples to the standard model (SM) through kinetic mixing. We note that for a small DM mass these decays are separately sensitive to DM couplings to quarks, but not its mass.

title: Width difference in the D0-anti-D0 system
abstract: The motivation most often cited in searches for D0-anti-D0 mixing lies with the possibility of observing a signal from new physics which dominates that from the Standard Model. We discuss recent theoretical and experimental results in D0-anti-D0 mixing, including new experimental measurements from CLEO and FOCUS collaborations and their interpretations.

title: Hadronic D and D(s) Meson Decays
abstract: We provide a comprehensive review of hadronic decays of D and D_s mesons. We discuss current theoretical and experimental challenges and successes in understanding of hadronic transitions of those mesons. A brief overview of the theoretical and experimental tools are given before discussing the absolute branching fractions for D and D_s mesons. Cabibbo suppressed and rare hadronic decays are discussed and compared with theory before discussing our understanding of hadronic multibody decays.

title: Long-distance effects in charm mixing
abstract: Flavor physics, especially physics of charmed mesons, oﬀers incredibly rich oppor-tunities not only to study soft Quantum Chromodynamics (QCD), but also searchfor glimpses of new physics (NP) [1, 2]. That search is only possible if the standardmodel (SM) predictions for experimental observables are known well, which meansthat uncertainties of theoretical predictions are understood and under control. Theexperimental observables, such as meson mixing parameters, rates and asymmetriesin rare decays and/or CP-violating asymmetries, are designed to provide likely placeswhere NP can be observed . Among those, a steady improvement of precision ofexperimental observation of D
