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?

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.
 
This is an alert about a claim regarding the standard model, that got a burst of attention in the past two weeks. The original paper came out last year: "The electroweak η_W meson" by Gia Dvali, Archil Kobakhidze, Otari Sakhelashvili (2024) The recent follow-up and other responses are "η_W-meson from topological properties of the electroweak vacuum" by Dvali et al "Hiding in Plain Sight, the electroweak η_W" by Giacomo Cacciapaglia, Francesco Sannino, Jessica Turner "Astrophysical...
this thread is to open up discussion on Gravi-GUT as theories of everything GUT or Grand Unified Theories attempt to unify the 3 forces of weak E&M and strong force, and Gravi-GUT want to add gravity. this peer reviewed paper in a journal on Gravi-GUT Chirality in unified theories of gravity F.

In LQG and LQC there are solutions called "black to white transition". I'll add some references: (Rovelli)https://arxiv.org/abs/1905.07251 (Rovelli)https://arxiv.org/abs/2302.03872 (Rovelli)https://arxiv.org/abs/1803.06330 (Rovelli)https://arxiv.org/pdf/1802.04264 (Rovelli)https://arxiv.org/abs/2108.12823 https://arxiv.org/abs/2304.02691 https://arxiv.org/abs/2110.07589 https://arxiv.org/abs/2009.01788 https://arxiv.org/abs/1911.12646 https://arxiv.org/abs/1801.03027...
