TRANSCRIPT
MVD coverage
Detailed MVD model
< 1% / layer ( < 10%)
MVD material budget
• Momentum resolution
p pt
1 GeV/c pions (0;0;0)
(pt) without MVD = 2.9 %(pt) with MVD = 1.4 %
(p) without MVD = 2.6 %(p) with MVD = 1.4 %
Improvement by 50%
• Single track resolution
No resolution along z without MVD
z xy
Momentum resolution
zxy z 65 m
15 GeV/c• Primary vertex resolution
• Vertex resolution Primary and secondary
vertex resolution: x,y 35 m
z 100 m
(6.57 / 7.50 / 8.50) GeV/c
Spatial resolution
