    The Brans-Dicke theory of gravity is one of the oldest ideas to extend general relativity by introducing a nonminimal coupling between the scalar field and gravity. The Solar System tests put tight constraints on the theory. In order to evade these constraints, various screening mechanisms have been proposed. These screening mechanisms allow the scalar field to couple to matter as strongly as ...

  3. cult to test these models with gravitational wave obser-vations [16]. Recently, a novel way to test scalar tensor theories was proposed using the gravitational wave memory [17]. The gravitational wave memory is a permanent change in spacetime geometry [18]. In GR, this is caused by a burst event, which creates a jump in the transverse-traceless

    FIG. 1. The function g(x) in Eq. (5). The dotted line shows the linear solution 2/x for x 1. Below the Vainshtein radius x < 1 the scalar field is suppressed due to the non-linear term. - "Testing Brans-Dicke gravity with screening by scalar gravitational wave memory"

    calculation of memory effect in alternative theories of gravitation, such as scalar tensor theory[35], Brans-Dicke theory [36,37] and Chern-Simons modified gravity[38]. Using the memory effect to test alternative theories of gravitation has also been studied, such as for the Brans-Dicke theory with screening [39].
