We reproduce the spectrum by summing a subset of the planar Feynman diagrams. We give a heuristic argument for why we can neglect other diagrams. We also discuss some other aspects of pp-waves and we present a matrix model associated to the DLCQ description of the maximally supersymmetric eleven dimensional pp-waves.","authors_text":"David Berenstein, Horatiu Nastase, Juan Maldacena","cross_cats":[],"headline":"","license":"","primary_cat":"hep-th","submitted_at":"2002-02-04T18:38:18Z","title":"Strings in flat space and pp waves from ${\\cal N}=4$ Super Yang Mills"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"hep-th/0202021","kind":"arxiv","version":3},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:6f0829167a6f42e5c6ed0f92c85048842a090fe6b95b929c488b625caa194cbd","target":"record","created_at":"2026-07-04T16:34:33Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"dc7085410e29905c3e8c07034e6da68dd81a2b45790f0a64e64ef4aa905e4517","cross_cats_sorted":[],"license":"","primary_cat":"hep-th","submitted_at":"2002-02-04T18:38:18Z","title_canon_sha256":"d7a6d824e8d7c7824e6f6085da25abc5f73acf372b93b326fa0c5dd83d636e23"},"schema_version":"1.0","source":{"id":"hep-th/0202021","kind":"arxiv","version":3}},"canonical_sha256":"719ab65056b8d493be53d4111ce12950aa20eac13e0f1c1729e0bad9e7d6638e","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"719ab65056b8d493be53d4111ce12950aa20eac13e0f1c1729e0bad9e7d6638e","first_computed_at":"2026-07-04T16:34:33.216912Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T16:34:33.216912Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"JZLuNhIGK1mzhEaiAXTej2uYfCWmfCs0iWo8O5GFdIHacTT7N9v/yVaM0jgvwmNer0cqyV9ylrh2+JLTJTGdBg==","signature_status":"signed_v1","signed_at":"2026-07-04T16:34:33.217259Z","signed_message":"canonical_sha256_bytes"},"source_id":"hep-th/0202021","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6f0829167a6f42e5c6ed0f92c85048842a090fe6b95b929c488b625caa194cbd","sha256:3536ce357c260814d74660adae47579574735e76809d6fb6c30651d2a7ab6b37"],"state_sha256":"1cb1366eb50fc949cf8057c7ee0f5e9e90fa11204235eaa2309cfc3e0ec3a009"}
