Force between static point particles coupled to a classical ultramassive scalar field is calculated. The field potential is proportional to the modulus of the field. It turns out that the force exactly vanishes when the distance between the particles exceeds certain finite value. Moreover, each isolated particle is surrounded by a compact cloud of the scalar field that completely screens its scalar charge. [ABSTRACT FROM AUTHOR]

We discuss building models for nucleon generalized parton distributions H and E that are based on the formalism of double distributions (DDs). We found that the usual "DD + D-term" construction should be amended by an extra term, ξE+¹ (x, &#958) built from the α/β moment of the DD e(β, β) that generates generalized parton distribution E(x, ξ). Unlike the D term, this function has support in the whole -- 1 = x = 1 region, and in general does not vanish at the border points │x│ =ξ [ABSTRACT FROM AUTHOR]

The modified scalar boson propagator due to the presence of a hyperplane semitransparent mirror is computed. From this, the classical interaction between static charges and the mirror is investigated employing delta-like potentials and sources. Although the calculations for hyperplane mirrors are performed in arbitrary dimensions, and in a completely general way, it is shown that the results give rise to the usual image method as a particular case. The interaction between a point-like mirror and a point-like source is also considered in 3 + 1 dimensions, where a central 1/R² attractive potential is also obtained as a special case.

The experimental data on the processes ππ→ ππ, KK, ηη, ηη' in the IGJPC = 0+0++ channel have been jointly analyzed to study the status and nature of the /0. The method of analysis is based on analyticity and unitarity and uses an uniformization procedure. Some spectroscopic implications from results of the analysis are discussed. [ABSTRACT FROM AUTHOR]

We observe that changing a phase at a single point in a discrete quantum walk results in a rather surprising localization effect. For certain values of this phase change the possibility of localization strongly depends on the internal coin state of the walker. [ABSTRACT FROM AUTHOR]

Harrison, Perkins and Scott have proposed simple charged lepton and neutrino mass matrices that lead to the tribimaximal mixing UTBM. We consider in this work an extension of the mass matrices so that the leptonic mixing matrix becomes Due to image rights restrictions, multiple line equation(s) cannot be graphically displayed., where Due to image rights restrictions, multiple line equation(s) cannot be graphically displayed. is a unitary matrix needed to diagonalize the charged lepton mass matrix and W measures the deviation of the neutrino mixing matrix from the bimaximal form. Hence, corrections to UTBM arise from both charged lepton and neutrino sectors. Following our previous work to assume a Qin-Ma-like parametrization VQM for the charged lepton mixing matrix Due to image rights restrictions, multiple line equation(s) cannot be graphically displayed. in which the CP-odd phase is approximately maximal, we study the phenomenologi implications in two different scenarios: Due to image rights restrictions, multiple line equation(s) cannot be graphically displayed. and Due to image rights restrictions, multiple line equation(s) cannot be graphically displayed.. We find that the latter is preferable, though both scenarios are consistent with the data within 3σ ranges. The predicted reactor neutrino mixing angle θ13 in both scenarios is consistent with the recent T2K and MINOS data. The leptonic CP violation characterized by the Jarlskog invariant J is generally of order 10-2. [ABSTRACT FROM AUTHOR]

A model-independent search for direct CP violation in the Cabibbo-suppressed decay D+ → K- K + π+ in a sample of approximately 370000 decays is carried out. The data were collected by the LHCb experiment in 2010 and correspond to an integrated luminosity of 35 pb-1. The normalized Dalitz plot distributions for D+ and D- are compared using four different binning schemes that are sensitive to different manifestations of CP violation. No evidence for CP asymmetry is found. [ABSTRACT FROM AUTHOR]

This article discusses the occurrence of one-loop amplitudes within a next-to-next-to-leading-order calculation. In a next-to-next-to-leading-order calculation, the one-loop amplitude enters squared and one would therefore naively expect that the 풪(ε)- and 풪(ε²)-terms of the one-loop amplitudes are required. I show that the calculation of these terms can be avoided if a method is known, which computes the 풪(&epsilon0)-terms of the finite remainder function of the two-loop amplitude.

Adiabatic processes driven by non-Hermitian, time-dependent Hamiltonians may be sped up by generalizing inverse engineering techniques based on counter-diabatic (transitionless driving) algorithms or on dynamical invariants. We work out the basic theory and examples described by two-level Hamiltonians: the acceleration of rapid adiabatic passage with a decaying excited level and of the dynamics of a classical particle on an expanding harmonic oscillator.

A fermiophobic Higgs boson can arise in models with an extended Higgs sector, such as models with scalars in an isospin triplet representation. In a specific model with a scalar triplet and spontaneous violation of lepton number induced by a scalar singlet field, we show that fermiophobia is not a fine-tuned situation, unlike in two higgs doublet models. We study distinctive signals of fermiophobia which can be probed at the LHC. For the case of a small Higgs mass, a characteristic signal would be a moderate B(H→γγ) accompanied by a large B(H→JJ) (where J is a Majoron), the latter being an invisible decay. For the case of a large Higgs mass there is the possibility of dominant H→ZZ, WW and suppressed H→JJ decay modes. In this situation, B(H→ZZ) is larger than B(H→WW), which differs from the SM prediction. [ABSTRACT FROM AUTHOR]

In this note, we study the coupling of the technidilaton to the weak bosons. We consider two cases: (1) The dilaton directly couples to the weak bosons in a similar way as in the standard model. (2) The coupling in question is effectively induced only through the technifermion loops. In both cases, we find that the coupling is essentially determined by the mass-squared of the weak bosons over the dilaton decay constant. [ABSTRACT FROM AUTHOR]
