Understanding pentaquarks with various quark models
Abstract We study the recently reported pentaquark state with three quark models which fit either nucleon spin structure or NN scattering data. The minimum Θ + ...

Anomaly-induced inflaton decay and gravitino-overproduction problem
Abstract We point out that the inflaton spontaneously decays into any gauge bosons and gauginos via the super-Weyl, Kähler and sigma-model anomalies in supergravity, once the inflaton acquires a non-vanishing vacuum expectation value. In particular, ...

Intersecting M2- and M5-branes
Abstract If an M2-brane intersects an M5-brane the canonical Wess–Zumino action is plagued by a Dirac-anomaly, i.e., a non-integer change of the action under a change of Dirac-brane. We show that this anomaly can be eliminated at the expense of a...

q-oscillator from the q-Hermite polynomial
Abstract By factorization of the Hamiltonian describing the quantum mechanics of the continuous q-Hermite polynomial, the creation and annihilation operators of the q-oscillator are obtained. They satisfy a q-oscillator algebra as a consequence of...

Interference bands in decays of doubly-charged Higgs bosons to dileptons in the minimal type-II seesaw model at the TeV scale
Abstract The dileptonic decays of doubly-charged Higgs bosons H ± ± ...

De Sitter in extended supergravity
Abstract We show that known de Sitter solutions in extended gauged supergravity theories are interrelated via a web of supersymmetry-breaking truncations. In particular, all N = ...

Revisiting 5D chiral symmetry breaking and holographic QCD models
Abstract We take a closer look at the recently discussed models of hadrons based on holographic ideas and chiral symmetry breaking in five dimensions. We study the two point correlator in detail and look at the field theoretic properties needed to...

Probing the natural broadening of hydrogen atom spectrum based on the minimal length uncertainty
Abstract The natural broadening of hydrogen atom spectrum based on the minimal length uncertainty is calculated. We will show that the natural broadening of hydrogen atom spectrum receives any correction.

Gauge dynamics in the PNJL model: Color neutrality and Casimir scaling
Abstract We discuss a gauge-invariant prescription to take the mean-field approximation self-consistently in the PNJL model (Nambu–Jona-Lasinio model with the Polyakov loop). We first address the problem of non-vanishing color density in normal...

Right unitarity triangles, stable CP-violating phases and approximate quark–lepton complementarity
Abstract Current experimental data indicate that two unitarity triangles of the CKM quark mixing matrix V are almost the right triangles with α ≈ 90 ° ...

Parton distribution uncertainties using smoothness prior
Abstract A study of the parameterization uncertainty at low Bjorken x ⩽ 0.1 for the parton distribution functions of the proton is presented. The study is ...

Possible violation of the spin-statistics relation for neutrinos: checking through future galactic supernova
Abstract We use the detection of neutrinos from a future galactic type-II supernova event in a water Cerenkov detector like Super-Kamiokande to constrain the possible violation of spin-statistics by neutrinos resulting in their obeying a mixed...

Holographic hadro-quarkonium
Abstract We consider the recently suggested model for some resonances near the open charm threshold as bound states of charmonium inside excited light mesons. It is argued in the soft-wall holographic model of QCD that such states of heavy...

Comments on ultra-high-energy photons and D-foam models
Abstract We revisit the constraints that the non-observation of ultra-high-energy photons due to the GZK cutoff can impose on models of Lorentz violation in photon propagation, following recent work by Maccione, Liberati and Sigl (2010)...

Calculation of Nuclear Contribution to the Zero-field Muon Spin Polarization Function of Single Crystal La2-XSrXCuO4
Abstract We calculate the zero-field muon spin polarization function P(t) of La2-xSrxCuO4 using a quantum mechanical model. The model includes the interaction between the positively charged muon and the nearby nuclei, and the effect of the crystal...

Cross section evaluation in the photodisintegration of152Sm isotope
Abstract We have evaluated the cross section of the 152Sm(γ, n)151Sm reaction in the frame of the Hauser – Feshbach formalism using the Talys computer codes as well as by using the computer codes written by the authors. The obtained results were...
