Chaotic inflation with fourform couplings
/ Lee, Hyun Min (ChungAng U.)
We consider chaotic inflation models with a pseudoscalar field containing the general couplings to the fourform flux. The fourform mixing with the pseudoscalar field induces a quadratic potential for inflaton while the coexisting fourform mixing with graviton generates a nonminimal gravity coupling for inflaton.

Relaxation of Higgs mass and cosmological constant with fourform fluxes and reheating
/ Lee, Hyun Min (ChungAng U.)
We consider the most general effective action for the fourform fluxes in the Standard Model coupled to gravity. The Higgs mass parameter can be relaxed to a correct value due to the fourform coupling to the Higgs field and it stops changing due to an extremely suppressed transition probability from the observed cosmological constant to AdS space.

Algorithms and tools for iterated Eisenstein integrals
/ Duhr, Claude (CERN) ; Tancredi, Lorenzo (Oxford U., Theor. Phys.)
We present algorithms to work with iterated Eisenstein integrals that have recently appeared in the computation of multiloop Feynman integrals. These algorithms allow one to analytically continue these integrals to all regions of the parameter space, and to obtain fast converging series representations in each region. [...]

Generalized covariant prescriptions for averaging cosmological observables
/ Fanizza, Giuseppe (INFN, Pisa ; U. Lisbon (main)) ; Gasperini, Maurizio (Bari U. ; INFN, Bari) ; Marozzi, Giovanni (Pisa U. ; INFN, Pisa) ; Veneziano, Gabriele (CERN ; College de France)
We present two new covariant and general prescriptions for averaging scalar observables on spatial regions typical of the observed sources and intersecting the past lightcone of a given observer. One of these prescriptions is adapted to sources exactly located on a given spacelike hypersurface, the other applies instead to situations where the physical location of the sources is characterized by the experimental "spread" of a given observational variable. [...]

Light quark masses in N_f = 2+1 lattice QCD with Wilson fermions
/ Bruno, Mattia (CERN) ; Campos, Isabel (Cantabria Inst. of Phys.) ; Fritzsch, Patrick (CERN) ; Koponen, Jonna (KEK, Tsukuba) ; Pena, Carlos (Madrid, Autonoma U. ; Madrid, IFT) ; Preti, David (INFN, Turin) ; Ramos, Alberto (Trinity Coll., Dublin) ; Vladikas, Anastassios (INFN, Rome2)
/ALPHA Collaboration
We present a lattice QCD determination of light quark masses with three seaquark flavours ($N_f = 2+1$). Bare quark masses are known from PCAC relations in the framework of CLS lattice computations with a nonperturbatively improved WilsonClover action and a treelevel Symanzik improved gauge action.

Longrange electroweak amplitudes of single hadrons from Euclidean finitevolume correlation functions
/ Briceño, Raúl A. (Jefferson Lab ; Old Dominion U. (main)) ; Davoudi, Zohreh (Maryland U. ; Wako, RIKEN) ; Hansen, Maxwell T. (CERN) ; Schindler, Matthias R. (U. South Carolina, Columbia) ; Baroni, Alessandro (U. South Carolina, Columbia ; Los Alamos Natl. Lab., Theor. Div.)
A relation is presented between singlehadron longrange matrix elements defined in a finite Euclidean spacetime, and the corresponding infinitevolume Minkowski amplitudes. This relation is valid in the kinematic region where any number of twohadron states can simultaneously go on shell, so that the effects of stronglycoupled intermediate channels are included. [...]
