Jun 1, 2019 at 19:13 | comment | added | Nogueira | the massless gluons are described by open strings with BOTH endpoints at the stack n. | |
May 31, 2019 at 17:24 | comment | added | Angela | And the open ended strings beginning and ending in ngs stack the massless gauge bosons? (the gluons?) | |
May 31, 2019 at 17:18 | comment | added | Nogueira | the ending points of the stretched string is the W-boson in double line notation. | |
May 31, 2019 at 17:10 | comment | added | Angela | The string that interpolates the stacks represents the rest mass of the gauge bosons? (W bosons)? | |
May 29, 2019 at 18:46 | comment | added | Nogueira | The strings that interpolates the stacks does acquires mass due to the Higgs, but in the decoupling limit we only want to consider the interaction of open strings, not open+closed, so this stretched string will not deform the background since this comes from open+closed interactions. This is in SYM side of the duality. In the AdS side of the duality the stretched string does interact with close strings of the AdS, since close strings in AdS are dual to open strings of the SYM side. | |
May 29, 2019 at 10:30 | comment | added | Angela | So, in short, are you saying that, though $ng_s$ acquires mass due to Higgs mechanism, it will not affect the $ADS_5$ space time since string tension $\alpha \rightarrow 0$. And $\alpha \rightarrow 0$ leads to negligible interaction between the bulk and brane ($ng_s$ branes). | |
May 28, 2019 at 16:24 | comment | added | Nogueira | Considering the embedding of strings ending in the stack $n$ on the Ads space-time will be dual ro the interaction of theses opens strings solely with the open strings of the stack $N$, while considering the background response of the open strings that sttraches between the stacks will be dual to the interaction of the open strings living in the stack n with the close strings, but the decoupling limit turn this off. | |
May 28, 2019 at 16:19 | comment | added | Nogueira | Now, the strings that interpolate the stack will become massive, but at the same time you should realize that the you are at the decoupling limit, so you are turning down the interaction between open and close strings in the SYM side of the duality. | |
May 28, 2019 at 16:13 | comment | added | Nogueira | You should realize that there are two sourcers of gravity: The stack $N$ and the stack $n$. Both couples with gravity proportionally with the $g_s$. Keeping $ng_s$ small will guarantee that the stack of n D3-branes will not deform thr background. | |
May 27, 2019 at 15:02 | comment | added | Angela | Looking at it from a different perspective. The 5th dimension in $AdS_5$ is energy. When you take the ngs branes to near horizon, you are taking it to energy infinity. This process of higgsifying it and taking it to infinity, makes it acquire large mass. Why wont an extremely large energy string modify the space time around it? ngs was smaller energy than Ngs before higgsifying it, and not after. | |
