BRAND: Search for BSM physics at TeV scale via the transverse polarization of electrons emitted in neutron decay - beam time extensio
The basic goal of the proposed project is the construction of the apparatus and carrying out of data taking in an innovative experiment measuring simultaneously as many as 11 correlation coefficients in the decay of polarized neutrons. Five from them (H, L, S, U, V) would be measured for the first time. The ultimate goal of the project is the determination of the correlation coefficients H, L, N, R, S, U and V with the accuracy of about 5x10^{-4}, and providing complementary and competitive information respectively to ``classical'' neutron decay experiments (correlation coefficients a, b, A, B, D) and to ongoing and planned high-energy experiments (like eg. CMS at LHC) searching for not existing in the Standard Model but theoretically possible scalar and tensor couplings. The request for additional 2 weeks of beam time is a result of a rearrangement of the orginal plans imposed by a substantial delay in delivery of the beam time allocated within the proposal 3-07-384: the first (out three) weeks will begin on September 21, 2020. The requested beam time will be devoted for taking data necessary for complition of ongoing PhD projects.
