Do superstrings exist in two states of spin?

[epmc2]

As you could probably tell, my question is whether or not a superstring could exist with two different types of spin, if they have a spin at all?

Do superstrings exist? Firstly you must decide is "string theory" is a model vs. a supposition about reality. Second you must determine if such a supposition about reality is operationally meaningful. But all such philosophical qualifications aside...

Yes strings can have spin and the "super" in "super-string" unifies integer and half-integer spin within the ... "model"? ..."theory"?

One way to invoke intrinsic spin in a string is to allow the quantized vibrational excitation correspond to a wave traveling around the loop of a closed string. This traveling vibration will carry a momentum and thus an angular momentum about the string's loop. Higher energy excitations will thus carry higher integer units of angular momentum.

So what about the spin of open strings?

So what about the spin of open strings?

thats what i thought thanks.
but ya... what about open strings if they exist?

Sure them too. As they are not points but extensive objects giving them spin is a simple matter.
