Measurement of the $B_s^0$ lifetime in the flavor-specific decay channel $B_s^0 \to D_s^- \mu^+\nu X$ / D0 Collaboration
We present an updated measurement of the $B_s^0$ lifetime from the D0 collaboration using the semileptonic decays $B_s^0\rightarrow D_s^-\mu^+\nu X$, with $D_s^- \to \phi \pi^-$ and $\phi \to K^+K^-$ (and the charge conjugate process). This measurement uses the full Tevatron Run II sample of proton-antiproton collisions at $\sqrt{s} = 1.96$~TeV, comprising an integrated luminosity of 10.4~fb$^{-1}$. [...]

Froissart Bound on Total Cross-section without Unknown Constants / Martin, André (CERN) ; Roy, S.M. (Tata Inst.)
We determine the scale of the logarithm in the Froissart bound on total cross-sections using absolute bounds on the D-wave below threshold for $\pi\pi$ scattering. E.g. [...]

Precision measurement of the mass and lifetime of the $\Xi_b^0$ baryon / LHCb collaboration
Using a proton-proton collision data sample corresponding to an integrated luminosity of 3 fb$^{-1}$ collected by LHCb at center-of-mass energies of 7 and 8 TeV, about 3800 $\Xi_b^0\to\Xi_c^+\pi^-$, $\Xi_c^+\to pK^-\pi^+$ signal decays are reconstructed. From this sample, the first measurement of the $\Xi_b^0$ baryon lifetime is made, relative to that of the $\Lambda_b^0$ baryon. [...]

Catching sparks from well-forged neutralinos / Bramante, Joseph (Notre Dame U.) ; Delgado, Antonio (Notre Dame U. ; CERN) ; Elahi, Fatemeh (Notre Dame U.) ; Martin, Adam (Notre Dame U.) ; Ostdiek, Bryan (Notre Dame U.)
In this paper we present a new search technique for electroweakinos, the superpartners of electroweak gauge and Higgs bosons, based on final states with missing transverse energy, a photon, and a dilepton pair, $\ell^+\,\ell^- + \gamma + \displaystyle{\not} E_T$. Unlike traditional electroweakino searches, which perform best when $m_{\widetilde{\chi}^0_{2,3}} - m_{\widetilde{\chi}^0_1}, m_{\widetilde{\chi}^{\pm}} - m_{\widetilde{\chi}^0_1} > m_Z$, our search favors nearly degenerate spectra; degenerate electroweakinos typically have a larger branching ratio to photons, and the cut $m_{\ell\ell} \ll m_Z$ effectively removes on-shell Z boson backgrounds while retaining the signal. [...]

Approach to equilibrium in weakly coupled nonabelian plasmas / Kurkela, Aleksi (CERN) ; Lu, Egang (McGill U.)
We follow the time evolution of nonabelian gauge bosons from far-from-equilibrium initial conditions to thermal equilibrium by numerically solving an effective kinetic equation that becomes accurate in the weak coupling limit. We consider initial conditions that are either highly overoccupied or underoccupied. [...]

B_{s,d} -> l+ l- in the Standard Model / Bobeth, Christoph (Munich, Tech. U.) ; Gorbahn, Martin (Liverpool U., Dept. Math. ; Munich, Tech. U.) ; Hermann, Thomas (KIT, Karlsruhe, TTP) ; Misiak, Mikolaj (Warsaw U. ; CERN) ; Stamou, Emmanuel (Munich, Tech. U. ; Weizmann Inst.) ; Steinhauser, Matthias (KIT, Karlsruhe, TTP)
We combine our new results for the O(alpha_em) and O(alpha_s^2) corrections to B_{s,d} -> l^+ l^-, and present updated branching ratio predictions for these decays in the standard model. Inclusion of the new corrections removes major theoretical uncertainties of perturbative origin that have just begun to dominate over the parametric ones. [...]

Measurement of the ratio of inclusive cross sections $\sigma (p\bar{p} \rightarrow Z+2~b~\text{jets}) / \sigma (p\bar{p} \rightarrow Z+ \text{2 jets})$ in $p\bar{p}$ collisions at $\sqrt s=1.96$ TeV / D0 Collaboration
We measure the ratio of cross sections, $\sigma(p\bar{p}\rightarrow Z+2~b~\text{jets})$/$\sigma(p\bar{p}\rightarrow Z+\text{2 jets})$, for associated production of a $Z$ boson with at least two jets with transverse momentum $p_T^{\rm jet} > 20$ GeV and pseudorapidity $|\eta^{\rm jet}| < 2.5$. This measurement uses data corresponding to an integrated luminosity of 9.7 fb$^{-1}$ collected by the \DO experiment in Run II of Fermilab's Tevatron \ppbar Collider at a center-of-mass energy of 1.96 TeV.

Infinitely many inequivalent field theories from one Lagrangian / Bender, Carl M. (Washington U., St. Louis ; King's Coll. London ; London, City U.) ; Hook, Daniel W. (Washington U., St. Louis ; Imperial Coll., London) ; Mavromatos, Nick E. (King's Coll. London ; CERN) ; Sarkar, Sarben (King's Coll. London)
Logarithmic time-like Liouville quantum field theory has a generalized PT invariance, where T is the time-reversal operator and P stands for an S-duality reflection of the Liouville field $\phi$. In Euclidean space the Lagrangian of such a theory, $L=\frac{1}{2}(\nabla\phi)^2-ig\phi\exp(ia\phi)$, is analyzed using the techniques of PT-symmetric quantum theory. [...]

$\mathbb R^3$ Index for Four-Dimensional $N=2$ Field Theories / Alexandrov, Sergei (Montpellier U.) ; Moore, Gregory W. (Rutgers U., Piscataway) ; Neitzke, Andrew (U. Texas, Austin (main)) ; Pioline, Boris (CERN ; UPMC, Paris (main))
In theories with $N=2$ supersymmetry on $R^{3,1}$, BPS bound states can decay across walls of marginal stability in the space of Coulomb branch parameters, leading to discontinuities in the BPS indices $\Omega(\gamma,u)$. We consider a supersymmetric index $I$ which receives contributions from 1/2-BPS states, generalizing the familiar Witten index $Tr (-1)^F e^{-\beta H}$. [...]

Study of beauty hadron decays into pairs of charm hadrons / LHCb collaboration
First observations of the decays $\Lambda_b^0 \to \Lambda_c^+ D_{(s)}^-$ are reported using data corresponding to an integrated luminosity of $3\,{\rm fb}^{-1}$ collected at 7 and 8 TeV center-of-mass energy in proton-proton collisions with the LHCb detector. In addition, the most precise measurement of the branching fraction ${\mathcal{B}(B_s^0 \to D^+D_s^-)}$ is made and a search is performed for the decays $B^0_{(s)} \to \Lambda_c^+ \Lambda_c^-$. [...]
