Temperature-Dependent Performance of NaI(Tl) Crystal with Dual-Channel SiPM Readout for Low-Mass Dark Matter Searches
W. K. Kim, H. Y. Lee, K. W. Kim +1
We report the first temperature-dependent characterization of a NaI(Tl) crystal readout by two silicon photomultipliers (SiPMs) directly coupled to opposite ends of the crystal for…
Gauge algebra and diffeomorphisms in string field theory
Raji Ashenafi Mamade, Barton Zwiebach
We consider the gauge algebra of closed string field theory with a focus on diffeomorphisms. This algebra contains off-shell information in two ways. The first way is geometric, th…
Type II RR string fields and exotic diffeomorphisms
Raji Ashenafi Mamade, Barton Zwiebach
We study the theory of massless fields of type II strings arising from the string field theory that uses two string fields, a physical one and an extra one that allows the writing…
Boundary terms in string field theory
Atakan Hilmi Fırat, Raji Ashenafi Mamade
We supplement the string field theory action with boundary terms to make its variational principle well-posed. Central to our considerations is the violation of the stress-energy t…
