Effective Field Theory descriptions of Higgs boson pair production

Higgs boson pair production is traditionally considered to be of particular interest for a measurement of the trilinear Higgs self-coupling. Yet it can offer insights into other couplings as well, since - in an effective field theory (EFT) parameterisation of potential new physics - both the production cross section and kinematical properties of the Higgs boson pair depend on various other Wilson coefficients of EFT operators.

Towards a test of the weak equivalence principle of gravity using anti-hydrogen at CERN
/ Banerjee, D (ETH, Zurich (main)) ; Biraben, F (Paris, Lab. Kastler Brossel) ; Charlton, M (Swansea U.) ; Cladé, P (Paris, Lab. Kastler Brossel) ; Comini, P (CSNSM, Orsay) ; Crivelli, P (ETH, Zurich (main)) ; Dalkarov, O (Lebedev Inst.) ; Debu, P (IRFU, SPP, Saclay) ; Dodd, L (Swansea U.) ; Douillet, A (Paris, Lab. Kastler Brossel) et al.
The aim of the GBAR (Gravitational Behavior of Antimatter at Rest) experiment is to measure the free fall acceleration of an antihydrogen atom, in the terrestrial gravitational field at CERN and therefore test the Weak Equivalence Principle with antimatter. The aim is to measure the local gravity with a 1% uncertainty which can be reduced to few parts of 10-3..

Optmized stability of a modulated driver in a plasma wakefield
/ Martorelli, Roberto (Heinrich-Heine U., Inst. Math.) ; Pukhov, Alexander (Heinrich-Heine U., Inst. Math.)
We analyze the transverse stability for a configuration of multiple gaussian bunches subject to the self-generated plasma wakefield. Through a semi-analytical approach we first study the equilibrium configuration for the modulated beam and then we investigate the evolution of the equilibrium configuration due to the emittance-driven expansion of the beam front that results in a rigid backward shift. [...]

The GBAR project (Gravitational Behaviour of Anti hydrogen at Rest) at CERN, aims to measure the free fall acceleration of ultracold neutral anti hydrogen atoms in the terrestrial gravitational field. The experiment consists preparing anti hydrogen ions (one antiproton and two positrons) and sympathetically cooling them with Be$^{+}$ ions to less than 10 μK. [...]

The performance of the CMS muon detector in proton-proton collisions at $\sqrt{s}$ = 7 TeV at the LHC
/ CMS Collaboration
The performance of all subsystems of the CMS muon detector has been studied by using a sample of proton--proton collision data at $\sqrt{s}$ = 7 TeV collected at the LHC in 2010 that corresponds to an integrated luminosity of approximately 40 inverse picobarns. The measured distributions of the major operational parameters of the drift tube (DT), cathode strip chamber (CSC), and resistive plate chamber (RPC) systems met the design specifications. [...]
