 On the Flavor Structure of Natural Composite Higgs Models & Top Flavor Violation / Azatov, Aleksandr ; Panico, Giuliano ; Perez, Gilad ; Soreq, Yotam We explore the up flavor structure of composite pseudo Nambu-Goldstone-boson Higgs models, where we focus on the flavor anarchic minimal $SO(5)$ case.

 The chiral phase transition in two-flavor QCD from imaginary chemical potential / Bonati, Claudio ; de Forcrand, Philippe ; D'Elia, Massimo ; Philipsen, Owe ; Sanfilippo, Francesco We investigate the order of the finite temperature chiral symmetry restoration transition for QCD with two massless fermions, by using a novel method, based on simulating imaginary values of the quark chemical potential $\mu=i\mu_i,\mu_i\in\mathbb{R}$.

 Dark matter direct detection constraints from gauge bosons loops / Crivellin, Andreas ; Haisch, Ulrich While many interactions of dark matter (DM) with the standard model (SM) affect direct detection and LHC searches, there are only a few operators generating annihilation of DM into photons.

 EFT Beyond the Horizon: Stochastic Inflation and How Primordial Quantum Fluctuations Go Classical / Burgess, C P ; Holman, R ; Tasinato, G ; Williams, M We identify the effective theory describing inflationary super-Hubble scales and show it to be a special case of effective field theories appropriate to open systems.

 Magnetization of fluid phonons and large-scale curvature perturbations / Giovannini, Massimo The quasinormal mode of a gravitating and magnetized fluid in a spatially flat, isotropic and homogeneous cosmological background is derived in the presence of the fluid sources of anisotropic stress and of the entropic fluctuations of the plasma.

 Muon g-2 Anomaly and Dark Leptonic Gauge Boson / Lee, Hye-Sung One of the major motivations to search for a dark gauge boson of MeV-GeV scale is the long-standing muon g-2 anomaly. [...] arXiv:1408.4256 ; CERN-PH-TH-2014-157. - 2014. - 5 p. Preprint - Full text

 Gravity and axions from a random UV QFT / Kiritsis, Elias It is postulated that the UV QFT is enormous and random. The coupling of the Standard Model to such QFT is analyzed.

 The NUHM2 after LHC Run 1 / Buchmueller, O ; Cavanaugh, R ; Citron, M ; De Roeck, A ; Dolan, M J ; Ellis, J R ; Flaecher, H ; Heinemeyer, S ; Malik, S ; Marrouche, J et al. We make a frequentist analysis of the parameter space of the NUHM2, in which the soft supersymmetry (SUSY)-breaking contributions to the masses of the two Higgs multiplets, $m^2_{H_{u,d}}$, vary independently from the universal soft SUSY-breaking contributions $m^2_0$ to the masses of squarks and sleptons.

 Pinning down compressed supersymmetric scenarios with monotop probes / Fuks, Benjamin ; Richardson, Peter ; Wilcock, Alexandra We investigate the sensitivity of the Large Hadron Collider to compressed supersymmetric setups by means of monotop events where a single top quark is produced in association with missing transverse energy.
