The positive lambda has a quark composition udc, and a lifespan of 2 x 10 minus 13 seconds. When this particle is created in a collision, inside a modern detector, how long will its track be? At near the speed of light, its lifetime would allow it to traverse less than a tenth of a millimeter. But, then, time dilation would extend that.

Additionally, are there any images available of the track of this particular particle, in either old bubble chamber photos, or modern digitally generated images from modern detectors?

The particle you mean is typically called ##\Lambda_c##. Lambda is uds.

Right. How much depends on the collider. The B-factories will typically give it a boost of about 2, LHC collisions will give it a typical boost of 5-10.

Bubble chambers will have a hard time measuring its track and modern particle detectors rarely work with images. Maybe someone made one for outreach, but you probably won't find it in publications.
 
Thank you all for the answers given to my question. I did check out the link provided by Vanadium 50.
