The cross sections are consistent with previous measurements at this collision energy, while the most forward and backward longitudinal single spin asymmetries provide new insights into the sea quark helicities in the proton. The charge of the W bosons provides a natural flavor separation of the participating partons.}, title = {Cross section and longitudinal single-spin asymmetry AL for forward W±→μ±ν production in polarized p+p collisions at √s=510??GeV}, volume = {98}, year = {2018}, yomi = {チュウジョウ, タツヤ and エスミ, シンイチ and ミアケ, ヤスオ and ニイダ, タカフミ and オザワ, キョウイチロウ} }
