Lattice QCD simulations directly at physical masses of dynamical light, strange and charm quarks are highly desirable especially to remove systematic errors due to chiral extrapolations. However such simulations are still challenging. We discuss the adaption of efficient algorithms, like multi-grid methods or higher order integrators, within the molecular dynamic steps of the Hybrid Monte Carlo algorithm, that are enabling simulations of a new set of gauge ensembles by the Extended Twisted Mass collaboration (ETMC). We present the status of the on-going ETMC simulation effort that aims to enabling studies of finite size and discretization effects. We work within the twisted mass discretization which is free of odd-discretization effects at maximal twist and present our tuning procedure.

Proton and neutron electromagnetic form factors from lattice QCD in the continuum limit
Nucleon electromagnetic radii and magnetic moments are extracted from lattice QCD in the continuum limit directly at the physical pion mass, with disconnected contributions included.

Isovector axial and pseudoscalar form factors from twisted mass lattice QCD at the physical point
From three physical-point twisted mass ensembles, the authors extract g_A, the axial radius, g_P^* and g_piNN in the continuum limit and report that PCAC and pion pole dominance hold.
