Title: Effect of Electron Irradiation on Superconductivity in Single Crystals of $Ba ({Fe}_{1 - x} {Ru}_{x})_{2} {As}_{2}$ ( $x = 0.24$ )

Abstract

A single crystal of isovalently substituted Ba(Fe_1-xRu_x)₂As₂ (x=0.24) is sequentially irradiated with 2.5 MeV electrons up to a maximum dose of 2.1×10¹⁹ e^-/cm². The electrical resistivity is measured in situ at T=22 K during the irradiation and ex situ as a function of temperature between subsequent irradiation runs. Upon irradiation, the superconducting transition temperature T_c decreases and the residual resistivity ρ0 increases. We find that electron irradiation leads to the fastest suppression of T_c compared to other types of artificially introduced disorder, probably due to the strong short-range potential of the pointlike irradiation defects. As a result, a more detailed analysis within a multiband scenario with variable scattering potential strength shows that the observed T_c versus ρ₀ is fully compatible with s_± pairing, in contrast to earlier claims that this model leads to a too rapid suppression of T_c with scattering.

Disorder-Driven Transition from $s_{\pm}$ to $s_{+ +}$ Superconducting Order Parameter in Proton Irradiated $Ba ({Fe}_{1 - x} {Rh}_{x})_{2} {As}_{2}$ Single Crystals

Journal Article Ghigo, Gianluca ; Torsello, D. ; Ummarino, G. A. ; ... - Physical Review Letters

Here, microwave measurements of the London penetration depth and critical temperature T_c were used to show evidence of a disordered-driven transition from s_± to s₊₊ order parameter symmetry in optimally doped Ba(Fe_1–xRh_x)₂As₂ single crystals, where disorder was induced by means of 3.5 MeV proton irradiation. Signatures of such a transition, as theoretically predicted, are found as a drop in the low-temperature values of the London penetration depth and a virtually disorder-independent superconducting T_c. We show how these experimental observations can be described by multiband Eliashberg calculations in which the effect of disorder is accounted for in a suitable way. Tomore »« less

Unconventional Charge Density Wave Order in the Pnictide Superconductor $Ba ({Ni}_{1 - x} {Co}_{x})_{2} {As}_{2}$

Journal Article Lee, Sangjun ; de la Peña, Gilberto ; Sun, Stella X. -L. ; ... - Physical Review Letters

Ba(Ni_1–xCo_x)₂As₂ is a structural homologue of the pnictide high temperature superconductor, Ba(Fe_1–xCo_x)₂As₂, in which the Fe atoms are replaced by Ni. Superconductivity is highly suppressed in this system, reaching a maximum T_c = 2.3 K, compared to 24 K in its iron-based cousin, and the origin of this T_c suppression is not known. Using x-ray scattering, we show that Ba(Ni_1–xCo_x)₂As₂ exhibits a unidirectional charge density wave (CDW) at its triclinic phase transition. The CDW is incommensurate, exhibits a sizable lattice distortion, and is accompanied by the appearance of α Fermi surface pockets in photoemission [B. Zhou et al., Phys. Rev.more »« less

Relative Modification of Prompt $ψ (2 S)$ and $J / ψ$ Yields from $p p$ to PbPb Collisions at $\sqrt{s_{N N}} = 5.02 TeV$

Journal Article Sirunyan, A. M. ; Tumasyan, A. ; Adam, W. ; ... - Physical Review Letters

The relative modification of the prompt ψ(2S) and J/ψ yields from pp to PbPb collisions, at the center-of-mass energy of 5.02 TeV per nucleon pair, is presented. The analysis is based on pp and PbPb data samples collected by the CMS experiment at the LHC in 2015, corresponding to integrated luminosities of 28.0 pb^-1 and 464 μb^-1, respectively. The double ratio of measured yields of prompt charmonia reconstructed through their decays into muon pairs, (N_ψ(2S)/N_J/ψ)_PbPb/(N_ψ(2S)/N_J/ψ)_pp, is determined as a function of PbPb collision centrality and charmonium transverse momentum p_T, in two kinematic intervals: |y|<1.6 covering 6.5<_pT<30 GeV/c and 1.6<|y|<2.4 covering 3<_pT<30more »« less

Sensitivity of the $η^{(')} \to π^{0} γ γ$ and $η^{'} \to η γ γ$ decays to a sub-GeV leptophobic $U (1)_{B}$ boson

Journal Article Escribano, Rafel ; Gonzàlez-Solís, Sergi ; Royo, Emilio - Physical Review D

The sensitivity of the rare decays η^(') → π⁰γγ and η' → ηγγ to signatures of a leptophobic B boson in the MeV–GeV mass range is analyzed in this work. By adding an explicit B-boson resonance exchange, η → Bγ → π⁰γγ, to the Standard Model contributions from vector and scalar meson exchanges, and employing experimental data for the associated branching ratios, it allows us to improve the current constraints on the B-boson mass mB and coupling to Standard Model particles α_B. From these constraints and the analysis of the available experimental γγ invariant mass distribution, we show that amore »« less
